Kassie is the second book in the Lovely Letters series and picks up where Prayer left off.

The wolf shifter Sebastian, who is the territorial alpha of the midwestern region and the alpha of the Black River Wolf Pack in Nebraska, has been shot multiple times. It was Prayer's ability to teleport him out of harm's way and into the capable hands of Kassie Lester that ultimately saved his life. Kassie Lester is a registered nurse who has devoted her entire life to the treatment of sick and injured animals in the wild.

After rescuing Sebastian, Kassie gives her word that she will return to Black River to help the fox pup who was shot and is unable to shift. Together, Kassie and Sebastian uncover even more betrayal inside the Supernatural Community. Kassie, with Sebastian's help and the encouragement of her new family, discovers new strengths as well as a number of her own latent talents and capabilities. Strengths and abilities, which she will test to the limit in order to find the answers she needs to protect the people she loves.

As mentioned above Kassie is a continuation of the Lovely Letters series and is not meant to be read as a stand alone.
