Isabelle of Kirklees has only ever known a quiet life inside the sheltered walls of the convent, where she lives with her mother, Marien. But after she is arrested by royal soldiers for defending innocent villagers, Isabelle becomes the target of the Wolf, King John’s ruthless right hand. Desperate to keep her daughter safe, Marien helps Isabelle escape and sends her on a mission to find the one person who can help: Isabelle’s father, Robin Hood.

As Isabelle races to stay out of the Wolf’s clutches and find the father she’s never known, she is thrust into a world of thieves and mercenaries, handsome young outlaws, new enemies with old grudges, and a king who wants her entire family dead. As she joins forces with Robin and his Merry Men in a final battle against the Wolf, will Isabelle find the strength to defy the crown and save the lives of everyone she holds dear?
