Eager to hide her own canny skill--a uniquely powerful ability to communicate with the fairy-like Good Folk--Neryn sets out for the legendary Shadowfell, a home and training ground for a secret rebel group determined to overthrow the evil King Keldec. During her dangerous journey, she receives aid from the Good Folk, who tell her she must pass a series of tests in order to recognize her full potential. She also finds help from a handsome young man, Flint, who rescues her from certain death--but whose motives in doing so remain unclear. Neryn struggles to trust her only allies. They both hint that she alone may be the key to Alban's release from Keldec's rule. Homeless, unsure of who to trust, and trapped in an empire determined to crush her, Neryn must make it to Shadowfell not only to save herself, but to save Alban. less

These four powerful beings have been increasingly at odds with human kind, and Neryn must prove her worth to them. She desperately needs their help to use her gift without compromising herself or the cause of overthrowing the evil King Keldec... moreNeryn has finally found the rebel group at Shadowfell, and now her task is to seek out the elusive Guardians, vital to her training as a Caller.
