23 1/2 Hours to Live (Only Hours #1)
Angela Kulig

Forced out of college Freshman year and into a dead end job, Kaylee doesn't become angry and bitter; instead she does her best to not even exist.
Here's a quick list of what Kaylee Hall expects from life:
1. Nothing
2. Nothing else
She doesn't date.
She doesn't make friends.
She doesn't feel anything.
So when the guy who ruined Kaylee's life in every way shows up and tries to casually rewrite her life story, she consults her list and doesn't know what to think.
Jack Claret has been called many things.
1. Hot
2. Really Hot
3. Prude
4. Slut
5. International Bestselling Author
6. Ruiner of virgin fangirls everywhere
and
7. Totally insane.
One thing Jack hasn't been called, is punctual. So when he shows up to win Kaylee back, he finds it's roughly a year too late. Relying on his powers of make-believe, and superior command of the English language, Jack seeks to undo the damage between them—even as Kaylee's whole world falls apart.
