The Girl on the Train by Paula Hawkins
My rating: 3 of 5 stars
Part of me can see the appeal of this, the acclaim it's received. But part of me doesn't quite: clearly the author is borrowing several old tropes (for example, a dash of Christie's 4:05 from Paddington) and not doing anything particularly original with them. I'm also tired of unlikeable narrators and while I grant that Rachel's alcoholism gives her the ability to make stupid decisions, like calling her ex multiple times a day/night, that didn't make her sympathetic.
