Vincent is the timid son of the last Whale Singer Humphrey whose mystical song is essential to the survival of the oceans. Vincent must master the song; however, he resists, disbelieving in his ability. When he accidentally frees a deep sea monster from its ice prison, his parents are killed. Now Vincent is the only one who can save the oceans. But rather than confront the dreaded monster himself, he travels to the deepest part of the ocean to retrieve his parents from the Star Pool, a mythical place where souls descend for eternity. Aided by Percy, his loyal cleaner fish, and Darya, a rambunctious orca girl, Vincent must learn to trust his (inner) voice and become a whale singer himself.
