Romane and Brahim have reached Algapower's artificial island, with the
help of some cetaceans with a quite extraordinary behaviour. All they
need to do now is sneak into the laboratories, locate Romane's kidnapped

especially as Algapower's found some ruthless allies. But the two
agents, too, have some rather unexpected allies - and a revolution is
coming...
