Except for Jill's mom and dad, no one knows that Kill transforms into a guy for four days a month. But now Jack (the guy) becomes more and more unruly and even escapes the house sometimes to spy on Jill's BFF. At the end of the story, Jill's friend and boyfriend accept what she really is.
If my friend was really into sci-fi or weird stuff, I would recommend this book. It did teach a lot about acceptance.

Jill has a huge secret -- Jack. He's the guy she turns into for four days each month. Jill's lies catch up to her as her secret gets too big to keep. But how can she tell people?
I found this story to be a bit creepy and predictable, although the message that the truth and good friend can get you through anything.
