'Old-school creepy… a five-star horror novel' STEPHEN KING on Ascension

Private Investigator Arlo Abbas is broke, between cases, and running out of reasons to get off the couch. Then £10,000 lands in his bank account from a stranger, with a note: Find Sophie Banik. But Sophie Banik is dead. No suspects, no family, the case forgotten.

His investigation pulls him underground through London’s tunnels and into the orbit of an organization whose strange experiments blur the boundaries between sleep and wakefulness, between life and death. Whoever sent the money didn’t just want Arlo to find Sophie. They wanted him to find what she’d discovered.

Now Arlo must decide how deep he’s willing to dig into the case, the conspiracy, and the parts of his past he’s spent years trying to bury. Because he’s starting to suspect Sophie Banik might not be as dead as everyone thinks.
