Survivors - The escape begins

Action-packed deep-sea adventure from bestselling author Boris Pfeiffer
When Zacky wakes up in his crevice as usual, he knows immediately that something is wrong: It's warm and dark at the same time. The other laws on the reef also seem to be out of force, because with heat comes hunger, and with hunger comes a dangerous feeding frenzy. Not only Howler, the shark, is completely out of his mind and chases everyone who comes into his sights. They all search in vain for advice in the songs of their ancestors, but none of the songs tell of the bleaching of the corals or of the dangerous squids that hunger drives up from the depths. Only if the reef dwellers stick together is there any salvation ...
Tells of the dying of the coral reefs and the destruction of the sea as a habitat
