Edifying and entertaining evolutionary histories of alternate versions of Earth are interspersed throughout, granting the reader insight into the multiverse as the cracks between dimensions widen.

Things come to a head when Lee is kidnapped by a dodgy private security firm and then rescued by unknown allies who transport her through the multiverse, bringing her to join Kay, who has been recruited to save the world from a growing threat. Lee and Julian’s intricate story lines crisscross, building steady momentum and layered suspense. The last thing Julian expects to discover when he reaches the scene are Kay’s would-be abductors beaten senseless and camera footage of a woman who disappeared four years ago fleeing the building. Meanwhile, MI5 agent Julian Sabreur receives word that theoretical mathematician Kay Amal Khan has been attacked in her flat. Cryptid hunter Lee Pryor receives a call from her girlfriend, Elsinore “Mal” Mallory, four years after Mal disappeared without a trace on Bodmin moor. Tchaikovsky ( Children of Ruin) examines alternate dimensions and speculative evolution in this tropey, entertaining sci-fi adventure that’s both outrageously bizarre and utterly convincing.
