A DADDY FOR HER LITTLE PRINCE? 

Fredericka Devereaux is no pushover princess. She's determined to provide the best life possible for her infant son, Leo. So when her brother, the ruler of Chantaine, insists that she and her hearing-disabled son need a protector, Ericka objects. But her new bodyguard, handsome Treat Walker, warms her heart as he cares for her baby…and proves himself deserving of his name… 

Treat keeps telling himself that he's not into Ericka and her little family. She's stuck-up and a royal—hardly his type! Despite his best efforts, the former football player finds himself charmed by the sexy single mom and her adorable infant. This Christmas, all Treat wants in his stocking is the royal twosome he's sworn to protect!
