On the sleepy island of Tricliffe, whilst everyone is tucked up in bed, a military satellite is hurtling through the atmosphere, breaking apart and shedding its lethal cargo. In the black of night, within the dark heart of the shadows, Tricliffe’s beloved feline companions are changing, twisting and crunching. Come morning, the island will be forever changed.

Jake Mathews had been bubbling with excitement at the prospect of a long, lazy summer holiday. But in this new world, Jake and his friends must fight to survive against creatures only envisaged in nightmares. An armada of military warships are doing their best to evacuate the island before all hope is lost. Little do they realise, lurking beneath the waves lies something indestructible.

Even if Jake and his friends manage to survive the swarm of death scouring the island, the chances of escape, for them and the islanders, are practically impossible.
