The Thief's Mistress offers a new vision of the legend of Robin Hood and his lady love. Here is a warrior Marian, both valiant and vengeful. She has destroyed Simon of Vitry for his terrible crimes against her family, but his death has left her empty of purpose, her heart cold as a stone. Now, Eleanor of Aquitaine, mother of the imprisoned King Richard the Lion Heart, persuades her to go to Nottingham to spy on Prince John and the conniving Sheriff. Marian can cope with their nefarious schemes, but she finds herself torn between the seductive outlaw Robin who waylays her in Sherwood Forest, and the dark, brooding Guy of Guisborne.
