This is the story of a married couple that decided to see other people once a week to try to spice up their marriage . It’s no surprise when it doesn’t work out the way they planned .  I didn’t like either of the main characters and just couldn’t understand the hype till the last 50 pages of the book. It was a twisty ending that made me gasp out loud as I drove down the road! ( obviously and audio!) . That ending …just wow! It redeemed the book for me!
