First up is The Apprentice by Tess Gerritsen.
It is a boiling hot Boston summer. Adding to the city’s woes is a series of shocking crimes, in which wealthy men are made to watch while their wives are brutalized. A sadistic demand that ends in abduction and death.
The pattern suggests one man: serial killer Warren Hoyt, recently removed from the city’s streets. Police can only assume an acolyte is at large, a maniac basing his attacks on the twisted medical techniques of the madman he so admires. At least that’s what Detective Jane Rizzoli thinks. Forced again to confront the killer who scarred her—literally and figuratively—she is determined to finally end Hoyt’s awful influence . . . even if it means receiving more resistance from her all-male homicide squad.
But Rizzoli isn’t counting on the U.S. government’s sudden interest. Or on meeting Special Agent Gabriel Dean, who knows more than he will tell. Most of all, she isn’t counting on becoming a target herself, once Hoyt is suddenly free, joining his mysterious blood brother in a vicious vendetta. . . .
Filled with superbly created characters—and the medical and police procedural details that are her trademark—The Apprentice is Tess Gerritsen at her brilliant best. Set in a stunning world where evil is easy to learn and hard to end, this is a thriller by a master who could teach other authors a thing or two.
The Apprentice is the sequel to The Surgeon and probably shouldn't be read before reading the previous book. Luckily knowing The Surgeon's name doesn't really spoil the first book since you get his name right as you read who he is. So, really, no spoils there for any worriers.
We've got Jane Rizzoli here again. She's an interesting character. I didn't actually like her much in the first book, but I learned a lot more about her here and now do like her. The storyline is fairly fast-paced. I read most of it it today and enjoyed it enough to immediately head to the library to pick up the next two in the series - The Sinner and Body Double. I'd really recommend this series if you like police/medical thrillers. It offers a nice combo of them both.
