Under Ground

A page-turning locked-room mystery from the combined talents of Sarah Lotz and Louis Greenberg, writing as S. L. Grey.

It's JG Ballard meets Agatha Christie, with a soupcon of Patricia Highsmith thrown in. Grey rotates the viewpoint through the eyes of five very different characters, ramps up the tension to an almost unbearable level, and ends with a stunning double finale.

Under Ground shifts from slow-burn chills to its frantic finale with considerable expertise. A gripping book - and definitely not for the claustrophobic.

Under Ground is well paced and it certainly has the potential to become a classic thriller . . . It's full of well-developed characters, captivating twists and an unpredictable conclusion that will have any thriller fan guessing all the way through. A thoroughly enjoyable read

Atmospheric, readable and all too plausible. Under Ground is a grim, effective chiller that takes you to the edge and leaves you there

A complex survival murder mystery . . . A gripping and unpredictable thriller with many twists and turns.

Grey does a great job of sustaining that singularly unsettling sense that something awful is going to go wrong-and I dare say something is always going to go awfully wrong in The Sanctum . . . Under Ground is a brilliant jumping-on point for horror fans who haven't already gone Grey

Underground is essentially what would happen if Stephen King woke up one morning as Agatha Christie

Under Ground is a taught, tight and claustrophobic novel that uses its small cast of characters and the confined and limited narrative settings to great effect . . .It will grab your attention from the first chapter and have you hooked right up to the perfect ending

A fast-paced, slow-burn thriller . . . this is a gripping, briskly-paced novel of psychological suspense and the fragility of social norms. Grey's prose is superb, stripped down and briskly-paced, it keeps the novel moving forward

This book kept me on the edge of my seat, to the very end
