A Princess Under the Mistletoe (Royal Babies)

HER ROYAL CHRISTMAS SECRET 

Princess Sasha of Sergenia was born to rule, not change dirty diapers. But after threats force her family into exile, Sasha becomes "Sara," a nurturing nanny in Chantaine. Now, rather than having servants wait on her during holiday festivities, Sasha is caring for construction specialist Gavin Sinclair's children for Christmas. Baby Adelaide and five-year-old Sam win her heart, but their father makes her pulse pound… 

For Gavin, "Sara" is a holiday miracle. Since his late wife died in childbirth, Gavin has struggled to keep his life afloat and his family together. This unexpected addition has brightened his world—and made him wonder if love might be on the horizon. He knows the mysterious nanny has secrets aplenty. But is true love enough to create a fairy-tale ending under the mistletoe for the sexy single dad and the lovely royal?
