Fans of Sarah Dessen and Morgan Matson will be swept away by this big-hearted story about one girl navigating first loss and first love during her summer on Cape Cod.

Saving the whales has been Coriander Cabot and her best friend Ella's dream since elementary school. But when tragedy strikes, Cor is left to complete the list of things they wanted to accomplish before college alone, including a marine biology internship on Cape Cod.

Cor's summer of healing and new beginnings turns complicated when she meets Mannix, a local lifeguard who completely takes her breath away. But she knows whatever she has with Mannix might not last, and that her focus should be on rescuing the humpback whales from entanglement. As the tide changes, Cor finds herself distracted and struggling with her priorities.

Can she follow her heart and keep her promise to the whales and her best friend?
