Blurb:
Cole and Ava have been best friends since they were kids. But one drunken night changes everything, and now Ava can barely tolerate being around him. The problem is that they’re roommates, and Ava doesn’t want to move.
 
Cole wants to explain what happened to Ava, but she refuses to listen. It isn’t until they both get sick and are forced to be around each other that he might have a chance at straightening things out.
 
But now things are on hold as Ava fights for guardianship of her little sister. Will they survive the emotional toll of a custody battle and their tumultuous friendship?
