I was looking for a quick trashy book to read and stumbled across this. It fit the bill.
This book (more of novella length than novel length) was written entirely as a series of text messages. The texts are between Megan and Ryan, her lover. And between Megan and Steven, her husband.
Fortunately it was a short book because the texts started sounding all alike. It had a rather predictable ending. There was some graphic sex talk in it so it is definitely not a YA book.
It was an okay read for a quick book to fill a couple of hours. Not a great book. But not an awful book.
