Tara Hartnell loves her best friend, Kelly Martin, but Kelly's older brother Mason has been her worst enemy since grade school. Now Mason's back from active duty in the Middle East, and Tara's visiting the Martins for Christmas. Can they call a truce for the weekend or will close quarters spark World War III?

The death of her parents and Kelly's marriage have made this a difficult year for Tara. The last few months have been the loneliest of her life. Mason's advances don't help matters, especially since she's convinced they're a setup to yet another of his tricks. She's come prepared, however, and she's determined to get the revenge she's been waiting for since sixth grade.

Mason's had more than his fair share of combat experience, but he never expected Tara to be such a cunning adversary. All he wants is a kiss, but getting close to her is like fighting his way through a minefield. Now it's time for the Martins' oldest family tradition: Christmas Eve paintball. Can Mason finally capture the woman of his dreams, or will Tara's plans for revenge succeed all too well?
