Forced to learn the killing arts from a religious assassin, Italian perfumer and apothecary Allegra Grimaldi has sworn never to use her deadly skills. But now a blackmailer has her by the proverbial throat. To save her family, she must do the unthinkable. Infiltrate the court of King Henry VIII, poison the heretic Anne Boleyn before she becomes queen--and frame Anne''s bastard brother for the crime. Allegra is clever, captivating...and her warning to Anne immediately rouses Joscelin''s suspicion. Sworn to protect his sister, and striving for recognition from the powerful father who disdains him, Joscelin has no choice but to put aside his attraction to the mysterious lady and gather evidence to see her burn for witchcraft. To avert a disaster that will change the face of Europe, this stalwart soldier of incorruptible integrity and the fallen woman who breathes deception must learn to trust each other--and discover the one truth that could save them all.
