In this sixth and concluding book of the Tunnels series, the Styx and their cohorts of deadly Armagi have swept across England, leaving death and devastation in their wake. It seems nothing can stop them now. Only a miracle can save the day and, in the inner world at the centre of the earth, Will and Elliott might just have stumbled upon one as they uncover ancient secrets that are fundamental to al human and Styx life.

The New York Times best-selling Tunnels series continues with this fifth installment from acclaimed authors Roderick Gordon and Brian Williams. In Spiral, horror spreads across England in the form of the Styx, malevolent creatures carrying a dark secret that could spell doom for all Topsoilers. All is not lost, however. Will Burrows and a small band of former commandos vow to stomp out the threat - even if it means placing their lives in mortal danger.
