Thief’s Covenant (#1)

Next: False Covenant (#2)

Once she was Adrienne Satti. An orphan of Davillon, she had somehow escaped destitution and climbed to the ranks of the city’s aristocracy in a rags-to-riches story straight from an ancient fairy tale. Until one horrid night, when a conspiracy of forces—human and other—stole it all away in a flurry of blood and murder. Today she is Widdershins, a thief making her way through Davillon’s underbelly with a sharp blade, a sharper wit, and the mystical aid of Olgun, a foreign god with no other worshippers but Widdershins herself. It’s not a great life, certainly nothing compared to the one she once had, but it’s hers.
But now, in the midst of Davillon’s political turmoil, an array of hands are once again rising up against her, prepared to tear down all that she’s built. The City Guard wants her in prison. Members of her own Guild want her dead. And something horrid, something dark, something ancient is reaching out for her, a past that refuses to let her go. Widdershins and Olgun are going to find answers, and justice, for what happened to her—but only if those who almost destroyed her in those years gone by don’t finish the job first. 


“For teens already reading adult fantasy but wanting something a bit more on their level, this hits the spot perfectly.”


“Marmell knows how to write a compelling book: smart, smartmouthed irreverent, and bold female thief with an vivid world for her to inhabit and a memorable cast of characters. It is swashbuckling fun to watch Widdershins make her way in the world.”

Night Owl Reviews, a 2012 top pick

“Widdershins is not your average heroine. Adept with her blade and her wits, sassy and sensitive, she should appeal to older teens both male and female.”

“Like a gateway drug for GAME OF THRONES […] There is a wonderfully rich flavor to this YA fantasy, with its Renaissance inspired setting, personal pantheon of deities, and dark tone (it even dips a toe in the realm of horror). This is a story with satisfying heft, texture, grit and originality, and I really, really enjoyed reading it.”

Book Yurt

“A fantastic new fantasy full of swashbuckling adventure, interesting characters, and a plot that unfolds like a mystery. This new series has a lot of potential with plenty of action, humor, drama, and magic. This series is marketed toward young adults, but more mature fantasy fans will enjoy this fun and enchanting story as well.”
