“When marine biologists unlock the first two-way conversation with dolphins, they uncover a secret on the ocean floor that was never supposed to be found — and someone will kill to keep it buried.”
A compulsively readable science adventure series that combines talking dolphins, government conspiracies, and genuine evolutionary science into six books of escalating wonder.
