Edinburgh is basking in an unnaturally warm winter until the snow starts falling. When a student disappears, along with his climate research, and the national government close down all communications, Professor Finlay Hamilton realises there is a link between his own research into dark matter and the freak weather. Suddenly he is in a desperate race to save his wife, Jess, and their young family from a catastrophic event. His only help is a man from Jess's past, a past he never knew existed.
From the author of Whirligig: longlisted for the CWA John Creasey New Blood Dagger 2020 and shortlisted for the 2020 Bloody Scotland McIlvanney Prize, something completely different - an environmental thriller like no other.
