I liked The Likeness - I really did. It just didn't quite live up to In The Woods in my opinion. But I partly blame my lesser enthusiasm on the fact that I listened to this one on audio. I'm a total audiobook convert, but some things just aren't meant to be listened to, and character-driven murder mysteries is one of them. While the narrator was great and really brought Cassie to life, I couldn't help but zone out at times, and retracing steps in audiobooks isn't quite as easy as flipping back pages and rereading paragraphs. I wouldn't say I missed anything pivotal to the plot - just that maybe French's beautiful writing and intricate details didn't quite come through via audio. 
 All that being said, despite the really implausible storyline, I felt just as pulled into The Likeness as I did for In The Woods. I cared about Cassie and wanted her to find peace, and while many are probably on the Rob train, I really loved Sam. (view spoiler)[I was convinced for about half the book that Frank was some crazy dude that was obsessed with his undercover agent's alias and wanted to bring her to life through said agent, by the end I really appreciated his character and was excited to see he's the focus of a future book. I'm not sure that's actually a spoiler because I think it might've been a crazy theory, but gotta hide it just in case! (hide spoiler)]. Looking forward to reading more of Tana French!
