Christmas was supposed to be about joy and hope…not about thwarting terrorist plots Most covert agents weren't blessed with long careers. Mike Becker wasn't like most agents. On the cusp of early retirement, he's given one final assignment: babysit a single mother with a reputation for coming up with conspiracy theories. Except the bullets flying Claire Chadwick's way can't be dismissed. Now Mike will do anything to protect her and her son, and uncover the truth. A truth that places them at the center of a terrorist attack on Christmas Day. Mike's career may be coming to a blazing finish, but in this woman he finally has a shot at the redemption that's eluded him for so long.

CHRISTMAS UNDER THE COVERS Take-charge undercover operative Zachary Steele hated playing the role of accommodating secretary to boss lady Chloe Betancourt. But the engaging Southern belle was the prime suspect in his current investigation—and the prime source of his sleepless nights. Because to get close to his subject, Zach had agreed to act as her holiday escort. Heck, he'd even suggested a pretend proposal! But when his "betrothed" learned he was doing double duty as a secret agent Santa, would he get the big kiss-off? Or would Chloe seal their future with a kiss under the mistletoe?

Santa and his little helper, newly qualified X.M.A.S. agent Jingle Bells, are on the trail of Dr Cumulus Nimbus, who's hell-bent on creating a new ice age - and Santa hates snow! Can they stop the evil plot before the world is snowed under?

Covert agent Mike Becker's last assignment is to protect single mother Claire Chadwick and her son, a task that places them all at the center of a terrorist attack on Christmas day.
