Book: Happens Every Day: An All-Too-True Story by Isabel Gillies
About: Gillies (who plays Detective Stabler's wife on Law & Order: SVU) writes about her seemingly perfect marriage that dissolved with astonishing quickness after her husband starts fancying his new colleague who also happens to be one of Gillies' best friends.
Pros: Engaging story and short chapters resulted in "just one more chapter..." syndrome.
Cons: She keeps mentioning that she and the entire Oberlin community is very liberal. You don't need to keep telling us. Commits one of my most hated writing pet peeves by using "had had" on page 52 of the hardcover.
