The Naturalist – Data Science takes on serial killers

Goodreads for each book: 1: 4.05, 2: 4.29, 3: 4.25, 4: 4.19

A different type of serial killer hunter book. An interesting look at how to use AI to look through data for patterns and track killers. The main character is a little dark, but draws you in. The 2nd and 3rd books are probably the best in the series.

First Book Description: Professor Theo Cray is trained to see patterns where others see chaos. So when mutilated bodies found deep in the Montana woods leave the cops searching blindly for clues, Theo sees something they missed. Something unnatural. Something only he can stop.

As a computational biologist, Theo is more familiar with digital code and microbes than the dark arts of forensic sleuthing. But a field trip to Montana suddenly lands him in the middle of an investigation into the bloody killing of one of his former students. As more details, and bodies, come to light, the local cops determine that the killer is either a grizzly gone rogue…or Theo himself. Racing to stay one step ahead of the police, Theo must use his scientific acumen to uncover the killer. Will he be able to become as cunning as the predator he hunts—before he becomes its prey?

Lady Hardcastle – 1900’s English feminist cozy mysteries

Goodreads: 1: 3.89, 2: 4.10, 3: 4.27, 4: 4.28, 5: 4.37, 6: 4.03

A good, funny early 1900’s English Cozy Mystery with the always entertaining Lady Hardcastle battling it out to solve the latest mystery despite all the sexism she faces from all angle. Entertaining and endearing.  

First Book Description: Lady Emily Hardcastle is an eccentric widow with a secret past. Florence Armstrong, her maid and confidante, is an expert in martial arts. The year is 1908 and they’ve just moved from London to the country, hoping for a quiet life.

But it is not long before Lady Hardcastle is forced out of her self-imposed retirement. There’s a dead body in the woods, and the police are on the wrong scent. Lady Hardcastle makes some enquiries of her own, and it seems she knows a surprising amount about crime investigation…

As Lady Hardcastle and Flo delve deeper into rural rivalries and resentment, they uncover a web of intrigue that extends far beyond the village. With almost no one free from suspicion, they can be certain of only one fact: there is no such thing as a quiet life in the country.

Gibson Vaughn – Hero Hacker/ex-Marine thrillers

Goodreads for each book: 1: 4.17, 2: 4.05, 3: 4.16, 4: 4.2, 5: 4.33

“The Short Drop” was put on many Best Book of the Year lists in 2015. It doesn’t fit into a category too easily. Its an adventure/mystery/hacker story with political intrigue. It keeps you guessing. The rest of the series has a similar feel. Good stuff. 

First Book Description: For legendary hacker and marine Gibson Vaughn, the case is personal—Suzanne Lombard had been like a sister to him. On the tenth anniversary of her disappearance, the former head of Benjamin Lombard’s security asks for Gibson’s help in a covert investigation of the case, with new evidence in hand.

Haunted by tragic memories, he jumps at the chance to uncover what happened all those years ago. Using his military and technical prowess, he soon discovers multiple conspiracies surrounding the Lombard family—and he encounters powerful, ruthless political players who will do anything to silence him and his team. With new information surfacing that could threaten Lombard’s bid for the presidency, Gibson must stay one step ahead as he navigates a dangerous web to get to the truth.

John Rain – An asassin with principles

Goodreads: 1: 3.95, 2: 4.11, 3: 4.14, 4: 4.28, 5: 4.27, 6: 4.26, 7: 4.13, 8: 4.17, 9: 4.10, 10: 3.95

I don’t generally enjoy asassination stories, but the John Rain character and his supporting cast are unique, interesting, funny, and fantastically narrated by the author Barry Eisler. I highly recommend this series.   

First Book Description: Half American, half Japanese, expert in both worlds but at home in neither, John Rain is the best killer money can buy. You tell him who. You tell him where. He doesn’t care about why…

Until he gets involved with Midori Kawamura, a beautiful jazz pianist—and the daughter of his latest kill.

Mercy Kilpatrick – FBI  Agent and Oregonian Prepper

Goodreads for each book: 1: 4.15, 2: 4.27, 3: 4.31, 4: 4.44, 5: 4.48, 6: 4.54

I didn’t think I’d like this when I started, but 5 books in now I’m really enjoying it. The stories are good, there are strong characters including the female lead FBI agent Mercy, good narration, and learning about prepping has been way more fun than I though it would be. 

First Book Description: FBI special agent Mercy Kilpatrick has been waiting her whole life for disaster to strike. A prepper since childhood, Mercy grew up living off the land—and off the grid—in rural Eagle’s Nest, Oregon. Until a shocking tragedy tore her family apart and forced her to leave home. Now a predator known as the cave man is targeting the survivalists in her hometown, murdering them in their homes, stealing huge numbers of weapons, and creating federal suspicion of a possible domestic terrorism event. But the crime scene details are eerily familiar to an unsolved mystery from Mercy’s past.

Sent by the FBI to assist local law enforcement, Mercy returns to Eagle’s Nest to face the family who shunned her while maintaining the facade of a law-abiding citizen. There, she meets police chief Truman Daly, whose uncle was the cave man’s latest victim. He sees the survivalist side of her that she desperately tries to hide, but if she lets him get close enough to learn her secret, she might not survive the fallout…

Bobiverse – Fun Sci-Fi/AI/Space Opera

Goodreads for each book: 1: 4.29, 2: 4.38, 3: 4.4

I love the Bob. A great original story that has some interesting tech/science and is really fun. The first book is the best, but you want to know what happens in the other two. The legendary Ray Porter’s narration for this book is fantastic.  

First Book Description: Bob Johansson has just sold his software company and is looking forward to a life of leisure. There are places to go, books to read, and movies to watch. So it’s a little unfair when he gets himself killed crossing the street.

Bob wakes up a century later to find that corpsicles have been declared to be without rights, and he is now the property of the state. He has been uploaded into computer hardware and is slated to be the controlling AI in an interstellar probe looking for habitable planets. The stakes are high: no less than the first claim to entire worlds. If he declines the honor, he’ll be switched off, and they’ll try again with someone else. If he accepts, he becomes a prime target. There are at least three other countries trying to get their own probes launched first, and they play dirty.

The safest place for Bob is in space, heading away from Earth at top speed. Or so he thinks. Because the universe is full of nasties, and trespassers make them mad – very mad.

Morgan Dane – Small town lawyer

Goodreads for each book: 1: 4.03, 2: 4.29, 3: 4.40, 4: 4.43, 5: 4.41 6: 4.39

A really likeable series. Morgan Dane is a small town widowed mom with 3 young children. She decides to get back to work and fights for her clients with the help of some local PI’s.

Now, surrounded by family, she’s finally found peace and a promising career opportunity—until her babysitter is killed and her neighbor asks her to defend his son, Nick, who stands accused of the murder.

Tessa was the ultimate girl next door, and the community is outraged by her death. But Morgan has known Nick for years and can’t believe he’s guilty, despite the damning evidence stacked against him. She asks her friend Lance Kruger, an ex-cop turned private eye, for help. Taking on the town, the police, and a zealous DA, Morgan and Lance plunge into the investigation, determined to find the real killer. But as they uncover secrets that rock the community, they become targets for the madman hiding in plain sight.

Ryan Decker – Elite warrior fights sex trafficking

Goodreads for each book: 1: 4.01, 2: 4.31, 3: TBD

An interesting series. Its got some action in chasing down the bad guys, there’s something about the narration that is a bit light and funny, and it teaches a little bit about sex trafficking. 

First Book Description: Former CIA operative turned mercenary for hire Ryan Decker’s specialty is rescuing kidnap victims. Hired by an influential US senator to liberate her daughter from a human-trafficking ring, Decker never anticipated sabotage or that the assault could go so disastrously wrong. The hostage is dead. His team is wiped out, and so are their families, including Decker’s own wife and son—eliminated one by one by the Russian mafia. And he’s survived to take the fall.

When he’s inexplicably freed soon into a ten-year sentence in federal prison, Decker suspects another setup. And private investigator Harlow Mackenzie knows he’s right. She has evidence that a power greater than the Russian mob was behind the raid that ruined Decker’s life.

The next move in a nationwide cat-and-mouse game of high-level sedition is up to them. Fueled by revenge and an obsession to clear his name, Decker has only one mission: to destroy a growing conspiracy before it’s too late.
