Publisher's summary
Return to the incredible days of Ten this Christmas. ..

For the Tenth Doctor, the festive season always brought adventure.

In fact, he's saved Christmas across space and time more times than we ever knew...

Join the Doctor (and Donna and Martha and Rose, and other friends old and new) for incredible tales of daring and danger. From Daleks plotting to save humanity to Sycorax working to exploit it. . . from star-narwhals massing on the Moon to a toy factory in space.

Because even in the jolliest of seasons there's a world or two to save.
