This is the third book in Nora Roberts` Key trilogy in which three women (Mallory, Dana, and Zoe) are given 28 days to embark on a dangerous quest. If one of the women should fail, they will all lose their chance to find the key that unlocks each one`s destiny and her heart`s true desire. Here Zoe must summon up all her courage to complete the final, and perhaps the most dangerous, of the three quests.
