Unlike the previous MEG novels, which are years apart, this continues the story from part 4, HELL'S AQUARIUM. The two Megalodon siblings, Bela and Lizzy, have escaped and are near British Columbia, preying on Orcas. Jonas Taylor tries to recapture them. Meanwhile, Jonas' son David, is working for a Dubai Prince, who is creating a big aquarium zoo for similar prehistoric monsters. They are after a hundred foot Liopleurodon, which is even more ferocious than the giant Great White Sharks. However, Alten couldn't resist tying this tale into his unsatisfying VOSTOK novel, which also featured Taylor and fellow scientist in an alternate timeline/reality tale. It simply doesn't jibe with the giant shark tales-and reading about it again only irritated me.
I think this is a series that should soon have an end....
