Discover the magic of losing yourself in a book with this snappy fantasy adventure story, written for World Book Day by bestselling, award-winning author Kiran Millwood Hargrave.

Eira's always wanted to compete in the Wolf Trials. The winners become part of the Ryders, an elite group of warriors who ride gigantic sea wolves.

There's only one problem: Eira can't take part, because her mother is the fearsome Wolf Queen.

She won't let that stop her, though. Eira decides to disguise herself and compete . . . but will she succeed? Will she be recognised? And if she isn't, will she survive the Wolf Trials?
