The Girl on the Train

This was a nice wee change of pace from what I normally read. As a recovering alky myself, I could relate quite well to a lot of the main character's problems and it seemed pretty well researched in that respect. I never did have memories gradually come back though after blackouts. The author explains that short term memories aren't actually made, yet Rachel's memories gradually begin to return. I found that a little too easy of a device to reveal more of the plot.

The pacing was terrific though.
