Cover of The Hollow War by T. J. Hayes: a rat with a lantern and a fox with a sword beneath a glowing pink eye, at Burrow Cross station

Synopsis

Beneath London, something is waking up.

Beneath London lives a hidden civilisation of intelligent animals. They maintain the unseen boundaries between our world and the dark spaces beyond it.

When an old dimensional wound reopens in an abandoned Underground tunnel, a guilt-ridden rat maintenance worker is pulled into a war he never knew existed. It’s a war tied to the death of his best friend, the loss suffered by his pregnant wife, and a cult that believes ending existence is the only mercy left.

Horror that gets under the floorboards, not under the skin
