When her family moves to an island, she finally learns the truth—her father is a sea god, and she possesses extraordinary powers.
Caught between two worlds, Emily must navigate her newfound abilities while attending a secret underwater school alongside other half-human, half-mythical creatures. As she makes friends and enemies in the ocean depths, a dangerous force threatens both the human and magical realms. Emily realizes she's the only one who can bridge these worlds and stop an ancient evil from destroying everything she loves.
With her courage tested and her identity questioned, Emily embarks on an adventure that will define her destiny and prove that being different isn't a curse—it's her greatest strength.
