As a summer of swords approaches, everything Astrid hoped for is coming true. She's found her wolf. A war looms on the horizon-just what a young hero needs to make a name for herself. The path to becoming a warrior of legend is finally clear. Until strange powers awaken in Astrid and her wolf, Maera. Meanwhile, Queen Rosamund has made good on her promise of conquest since taking the throne. Thyrden's armies march for the Wolfmoors. Wielding forbidden magic, she's determined to succeed where her father could not. Nothing short of total victory will sate her ambition. As both sides ready for battle, Astrid and her friends find themselves far from the conflict, chasing after myths in the wilderness with an eccentric old matriarch. Their journey is nowhere near the glorious future Astrid had in mind. But not all is at it seems, even in the wild north. When tragedy strikes, Astrid risks everything to challenge Rosamund's dark magics. If Astrid and Maera hope to save the wolf riders, they'll have to trust in each other, and their newfound powers.
