HIGH PRESSURE OUTSIDE
On a boat heading out into the North Sea, Ellen Brooke steels herself to spend almost a month working underwater with five other divers. It is a close knit team and it has to be: any error or loss of trust in the living quarters could be catastrophic.

EXTREME PRESSURE INSIDE
All is going to plan until one of the divers is found unresponsive in his bunk. He hadn't left the chamber. It will take four more days of decompression, locked away together, before the hatch can be opened. Four more days of wondering if one among you is a killer. The constant struggle not to give way to panic. Because if someone does unlock the door, everyone dies...

Will Dean grew up in the East Midlands and had lived in nine different villages before the age of eighteen. After studying Law at the LSE and working in London, he settled in rural Sweden where he built a house in a boggy clearing at the centre of a vast elk forest, and it's from this base that he compulsively reads and writes. His debut novel in the Tuva Moodyson series, Dark Pines, was selected for Zoe Ball's Book Club, shortlisted for the Guardian Not the Booker prize and named a Daily Telegraph Book of the Year. Red Snow was published in January 2019 and won Best Independent Voice at the Amazon Publishing Readers' Awards, 2019. Black River was shortlisted for the Theakstons Old Peculier Award in 2021.
