The gap between the worlds was so thin in places, you could almost step across without meaning to... Lila Black can still turn into a lethal war-winning machine with the merest thought but she doesn't work for the agency any more. Problem is, she has no idea what to do next. Teazle is a demon who may have become Death's Angel. Zal is a has-been elven musician without a band. They don't add up to much and when they get together major stuff goes down. But the dead are walking, the veil between the worlds is tearing and if it fails altogether all bets are off. Someone has to do something and it looks like it's going to have to be Lila. Is attitude enough to get you through life and death? Will it get you a happy ending?
"Robson wraps up her highly inventive, often convoluted Quantum Gravity series with this complex tale that brings all the different elements of the story together in a satisfactory conclusion... The way this stellar urban fantasy unfolds is much like following a mobius strip as it twists and folds back upon itself while never failing to deliver plenty of surprises. The relationship between Lila, Zal and Teazle has been a fascinating centerpiece of the overall story and plays a large role in this last book of the series." (MonstersAndCritics)
