From Andrew Caldecott, the bestselling author of ROTHERWEIRD, comes the jaw-dropping conclusion of the MOMENTICON duology - an epic adventure like no other!

'Remember Simul' - the last words of a dying man, and the key to mankind's survival.

Words which take Morag, Fogg and their friends on a wild ride through caverns and over mountains, into old paintings, to a university unlike any other and up the lethal Tower of No Return. A ride where mythical beasts, legendary monster-hunters and a corrupt establishment lie in wait . . . while the weather-watchers look on and bide their time.

It's a race against extinction too . . . for nature herself is bent on vengeance.

'Special and dangerous properties . . . opens a series of trap-doors in the readers' imagination' Hilary Mantel, Booker prize winning author, on Rotherweird
