On the night of the new spring moon, a near-fatal accident propelled Victoria Reeves-Ashton over a century back in time to awaken in the body of Katherine Kamarov. Now, after three months of pretending to be Katherine and laboring to repair relationships damaged by Katherine's brash and selfish personality, quiet and gentle Victoria finds that her heart is putting down roots in Katherine's world, in her family relationships, and especially in a deepening friendship with Katherine's winsome cousin Michael.
Hidden letters reveal the story of other moonseed—time travelers like herself—and Victoria realizes that she and Katherine will likely be returned to their own times the following spring. Tension mounts when a rich and handsome suitor applies to marry her, and Victoria must choose whether to accept him for Katherine's sake or to follow her own heart.
Ryan Ashton, the husband Victoria left behind, is baffled by the woman his wife has suddenly become. Unwilling to believe her story about an exchange in time, Ryan struggles to understand the stark transformation of his timid, remote wife into a sexually aggressive and captivating siren. Against his better judgment, he falls hard for this new woman who is a perplexing mixture of cruelty, sensuality, and tenderness, a woman who he suspects has the power to either break his heart or heal the aching loneliness he has lived with all his life.
