Shadowlands

Serenity Walker's been in dire straits before, but things have gone from bad to worse, to hopeless. Stranded behind enemy lines in a wilderness poisoned by dark power, Serenity's out of options. With her magic stripped away and her weapons made useless, the rebel witch is every demon's prey. And the deadliest demon is her own. But there's more to fear than D'aej and his kind. Somewhere within herself, Serenity has stumbled on new memories. Memories that don't belong to her, but to the ancient, angry spirit at the heart of this cursed land. Hidden secrets overwhelm Serenity's mind, and lurking behind them, growing ever meaner, is a mad apparition that doesn't like the intrusion.
