In the quiet town of Mercy Falls, a tale of chilling romance unfolds between Grace and the mysterious Sam. Their connection is no mere coincidence; it is a bond as inexplicable as it is deep, for Sam is no ordinary boy but a wolf from the pack Grace has been observing. With each winter's approach, Sam must surrender his human form to the frozen woods, and each thaw holds the risk that he may never return to her. As Grace unravels the truth about the wolves in her town, love and courage collide in a desperate quest to keep Sam human forever.
