After the death of her sister years ago, Iris Caldwell tries to live a normal life in a town that feels frozen between seasons. Every so often, she catches glimpses of her sister — not alive, but a silent, ghostly figure that seems trapped between worlds. Iris doesn''''t realize at first that what she''''s seeing is real. The ghost never speaks, only lingers... and eventually begins to haunt others around her without explanation. Each year around Easter, Iris receives a mysterious note filled with cryptic symbols, as if someone — or something — is trying to communicate with her. But the meanings remain hidden, just beyond her understanding. As Iris grows older, the hauntings grow stronger, more desperate. The peaceful facade of the town cracks. Through a trail of visions, haunted memories, and finally deciphered clues, Iris uncovers the heartbreaking truth: her sister''''s death wasn’t an accident, and the ghost has been trying to lead her to the one person responsible. In the final confrontation, Iris must decide whether to bring the truth into the light — and risk tearing her family and town apart — or leave the past buried forever, along with her sister’s restless spirit.
