Fathom

When Aspen Matthews came to discover her true heritage, and her life beneath the waves began, her first mentor was the vicious Killian, who intended to turn her into a weapon which would destroy the world above the water utterly. Now Titan Books present Killian's story. Years before Aspen's birth, there is dissent amongst the ocean-dwellers. One of their cities has been unwittingly destroyed by humans, as a result of an atomic test. Rival factions clash over the right way to proceed, but, it seems, none of them wish for an all-out war. Even those who distrust and dislike humans - Killian included - know that to attack would lead to discovery, and chaos beyond their most awful imaginings. But when Killian discovers the terrible truth behind his parents' deaths, everything changes...forever...
