Read "I Found You" during the drive to and from Niagara Falls.
It's a chick book, boys. No need to read further.
I really enjoyed it. Lisa Jewell is a very good storyteller. Half way through I found myself comparing it to "A Girl On A Train", but it's not. It is suspenseful and kept me guessing throughout. And it turns out my guesses were not correct.
Don't want to give too much away, but.....
A single woman of 3 living on a seaside beach discovers a man on the beach one day. He has lost his memory and doesn't know who he is or where he is from. 60 miles away, a newly married woman's husband of 3 weeks disappears. The story bounces back and forth between them, and also to the same seaside town except 20 years in the past.
