Yara Jones has always felt connected to the sea surrounding her island home, but she never imagined she would become one of its creatures. After a hurricane, she wakes with fins—transformed by the mysterious merman Treygan—and pulled into an ancient conflict between merfolk and selkies. Both factions believe Yara holds the key to opening a sealed gateway between realms, but they disagree violently about what that will cost her.

Yara Jones is spontaneous, warm-hearted, and fiercely loyal—a girl who has always belonged to the sea without knowing why. Her humor and openness make her easy to love, though she must learn that belonging to two worlds means bearing the burdens of both.

Across The Sea Monster Memoirs trilogy, Yara navigates her new identity as a sea creature while uncovering the truth behind the broken promise that sealed the gateway and estranged the ocean races. The series weaves Greek mythology—Poseidon, Medusa, sirens, and gorgons—into a richly imagined underwater world where love, loyalty, and sacrifice are tested at every tide. Yara's growth from disbelieving outsider to the linchpin of oceanic peace drives the emotional arc of all three books.
