Both Jodi and Todd were boring as hell, I want to know more about Allison and her marriages, she seemed interesting.

Just a typical marriage, absolutely nothing riveting, although I am surprised Jodi's marriage seemed to fail despite her being a Psychologist.
Maybe that's the thrill?
A Psychologist fails to save her own marriage, despite listening to the problems of others?
I don't know.
Interesting book, monotonous, downright unmemorable characters though.

A.S.A Harrison wrote the story well, and I truly don't want to be redundant but it's just the characters were kind of boring, I wish she had made them more alive, they were so chilled.
