A rogue elven prince is determined to destroy the creatures who murdered his brother, but his plans are disrupted when a tribe of powerful shapeshifters join forces against him. Now a single human girl, Evanthe, is caught between the warring species, and both sides are searching for her. After accidentally stumbling into their world, Evanthe is kept hidden in the prince's own dungeon by one of his servants, a young mage named Delanor. All she really wants is to find a way to return home, for she knows it is only a matter of time before her whereabouts are discovered. But what weighs heavily on her mind even more than fear are the growing feelings she has for Delanor--and her dangerous attraction to the elven prince. When she receives a tantalizing offer from the enemy, she will have to choose sides not only in a war between nations, but between the allure of an immortal prince and the unconditional love of his servant.
