When a trip into the forest to collect a rare mushroom for her research goes horribly wrong, biologist Callie Peterson finds herself falling through a fairy portal and straight into the arms of tthe dangerously unhinged and viciously handsome Unseelie Fae prince. He thinks she’s an assassin sent by the humans to kill him, not a scientist, and he imprisons her in his realm—where unwillingly, unwittingly, his obsession with her begins to grow. He itches to feel her smooth skin, even though the Unseelie royals would rather burn than touch a human. If he does not destroy the girl soon, she may be the only thing capable of destroying him. Mendax needs to be rid of her—but he also needs to entertain his people. And so, he challenges Callie to three deadly trials. If she survives, she gains her freedom. If she doesn’t? His wrath is only just beginning.
