Body armor

the long version

"If last-minute shopping isn't killer enough, Santa is! When Anna Sanford is attacked by a vengeful Saint Nick, a mystery man saves her life. But the real mystery isn't why this man, Brody Carpenter, pledges to protect Anna through the holidays--it's why he left her in the first place ... and why she never told him she was pregnant with his child. In four turbulent years, he'd transformed from local sheriff into an international bodyguard for hire--and Anna is in serious need of protection. Brody wants to help her put her life back together, but dodging bullets is easier done than dodging the past ... especially when she is about to give him the ultimate Christmas surprise"--Publisher description.
