I'm terrible at making Best Of lists, because it seems like I read everything way early or way late, and I can never remember what came out when. But Crimespree's editor, Jon Jordan, asked me to contribute one, so I did. (It turns out only two of five books I listed came out in 2015. Four, if you count paperbacks. In my defense, I also often don't remember what day it is, how old I am, or where I set down my phone.)
Thankfully, everybody else at Crimespree Magazine is way more on the ball than I am, and they put together some terrific lists. Thanks to Ayo, Erica Ruth, Jon, Katrina (who may be biased since she's married to me, but in which direction?!), and Ruth for selecting THE KILLING KIND!
There are so many books on these lists I haven't read yet, but hope to soon. One that popped up on several, though, made me smack my head and wish I'd put it on my own: Sean Chercover's THE DEVIL'S GAME. To say I loved it is an understatement, so I've added it to my list in the comment section.
