It's not always easy, growing up as a human in Elfhelm—even if your adoptive parents are the newly married Mary and Father Christmas. For one thing, elf school can be annoying when you have to sing Christmas songs every day—even in July—and when you fail all your toy-making tests. Also, it can get very, very cold. But in this follow-up to A Boy Called Christmas, for readers 8 to 12, a jealous Easter Bunny and his Rabbit Army launch an attack to stop Christmas, it's up to Amelia, her new family, and the elves to keep Christmas alive—before it's too late.
