Highly bingeable domestic thriller/drama. I found the portayal of mental illness to be very well done in this book. 
At times every character in the 2 couples made me bonkers. Just the actions and reactions were… something. 

At the end I thought Pippa got away with not taking any responsibility for her role and the way she wrote off Gabe while talking to Max was… something “oh he’s too far gone then”, after the emotional & practical support he gave her seemed pretty ugly.
