"Will Treaty has come a long way from the small boy with dreams of knighthood. Life had other plans for him, and as an apprentice Ranger under Halt, he grew into a legend--the finest Ranger the kingdom had ever known. But now it's time to take on an apprentice of his own, and it's the last person he ever would have expected: his niece and goddaughter Maddie. But Maddie is more than Will bargained for, and with time, he must win the trust and respect...

"When Maddie and Will get a message that dire wolves--huge misshapen changelings, much larger than regular wolves--have been marauding and attacking through the hills and valleys of Celtica, the Rangers are sent on a mission to unravel just who or what is behind these dangerous creatures.
