One family is in for more than festive cheer in this new modern Christmas tale by bestselling author James Patterson.

It's not the conventional Christmas they're used to, but it may just be the Christmas the Sullivan family needs.

It's mid-December and for the fifth year in a row, there is little sign of the festive season in the Sullivan family's home in South London. That is until a mysterious someone starts sending strange gifts to widower Henry and his two children.

Before they know it, the Sullivans' home is full of boisterous animals and house guests, all demanding their attention.

The next twelve days turn the Sullivan family's lives upside down in ways they never could have imagined. But even though this Christmas will be messy, will it be just the gift their family needs?
