Gabriel Nemo is not your typical twelve-year-old.

A descendant of the famous Captain Nemo, he spent the first years of his life living in obscurity, isolated in his parents’ peaceful underwater research lab.

But with his older sister off following in their ancestor’s footsteps, sinking whalers and running away from vengeful navies, Gabriel decides it’s time to forge his own path, and use his Nemotech legacy for good.

But when Gabriel’s sister suddenly appears with proof of previously undiscovered sea creatures—giant beasts inhabiting wrecked war planes and ships—Gabriel and his new friends must face their biggest and most dangerous mission ever!
