In this darkly romantic companion to The Forest King's Daughter, a warrior princess finds herself in a strange shadow land where danger and secrets hide around every corner--and a mysterious shadow prince stands between her and the truth. Fearless Thea has never known life outside of war. As the favorite daughter of the Sylvan King, she's a relentless fighter who longs to lead his army as First Huntsman, ignoring the pretty clothes and fanciful notions others enjoy. But when a mysterious dress full of dark magic appears on her hearth one evening, Thea doesn't know how to fight an enemy she can't see or touch. Still, her curiosity builds as a new gown appears each night--until she gives in to temptation and is whisked to a forgotten land of shadows. The prince of the shadow realm is a handsome host, and while Thea does all she can to resist his charms, it's clear he knows something about the long-ago disappearance of Thea's mother. All he asks in return is for Thea to dance with him, their dangerous attraction growing each time she returns for more information. Meanwhile, shadows are seeping into the living realm, and Thea may have to embrace her own darkness if she has any chance of saving her beloved sisters and home from an otherworldly threat. From the author of the Frostblood Saga comes the second book in a spellbinding series about the daughters of the powerful forest king, with simmering romance and plot twists that will leave readers desperate to enter the Thirstwood themselves.
