Night Maze (en Inglés) - Helen Harper

It's one thing to be dealing death. It's quite another to deal with the undead.

Kit McCafferty has never been fond of vampires but she can't refuse the opportunity to learn more about their kind. When she is invited into the clandestine underground world of the Understream to investigate the mysterious disappearance of some giant worms, she soon discovers there is far more to the fanged creatures than she'd ever realised.

Danger, secrets and mysteries abound in every dark, twisting tunnel. Is there anyone in the depths who Kit can trust? Or will she have to rely on her wits - and her cats - alone?

This is the fourth book in the thrilling urban fantasy series The Cat Lady Chronicles.
