Tattoos bind the magic within him.

Journals hold the memories he can't recall.

How can you fight your demons when you don't know who you are?

Callum Foster, a queer man cursed with immortality and amnesia, has served the Library of the Damned for centuries. He lives an ascetic life, devoted to saving the unsuspecting public of 1990s London from the ravages of wild magic that strikes without warning and reduces lives to misery.

When young advertising executive Geoffrey Cooke vanishes and Chaos magic is suspected, Callum and the Library race to find him. He's discovered inexplicably unharmed in a nest of feral vampires, forcing Callum and Agent Biggs, Callum's brusque and deadly government counterpart, to put aside their hostility to stamp out this terrifying threat.

When powerful Chaos-kissed artifacts are stolen from the Library, Callum faces a sorcerous cabal serving the Crown who aim to discredit the Library and seize its assets. With a mysterious grimoire summoning horrifying demons, and a dangerous new breed of vampire on the loose, Callum must emerge from his shell, accepting help from strange new friends and lovers to save England from vampiric hordes.

But if Callum can't bridge the gap between his solitary existence and the allies he needs, the Library - and all of London - will be lost to the encroaching darkness.
