Query: An entertaining book

This is a story of two friends who get together to satisfy one another's sexual needs when they're not in relationships with others. It's plain to see to everyone except themselves that they really loved each other and not the other people that they dated. The book kept me entertained and I kept reading it to see what would happen next to place Case and Monica in each other's bedroom. This is definitely a book for a mature audience. Although there are a lot of sex scenes in here, I didn't find it to be too nasty. Nice job, Steph.
