When the asteroid blazed out of the atmosphere and buried itself in the ocean, it took Lieutenant Nathan Stone's new sonar system, his naval career, his hearing, and any hopes of a normal life with it. Driven into isolation by the painful legacy left by the asteroid accident, Stone discovers a new gift he must learn to control; a new ally in the form of a dark-masked man; and a new identity as Sonarr. Now Stone must use Sonarr's powers and identity to right the wrongs set into motion by the asteroid. Racing against time, he must save the life of a friend critically injured by the same accident and prove his own innocence in the face of unjust and corrupt accusations.
