I just finished
Girl on a Train, which is apparently the hot ticket right now, if the looks of my local B&N is any indication.
I'm sure it is being pitched as "if you liked
Gone Girl, you'll like this" -- and that is pretty apt. It also has substantial shades of
Rear Window and
Memento, I'd say. I find both female narrators and British accents/venues to be very slightly off-putting, but this overcame both of those easily.
Not a great great book, but well worth the time and cost, I'd say.
