Decades ago, Galactic Union envoy Siy Tarkov set off from the planet Valyshaa with vital information warning of an imminent Dalek invasion of the galaxy.

Twenty years later, and the only proof Tarkov ever existed is a garbled message, calling for help. But no-one is listening.

“...some kind of virus... disease... Am putting myself into cryogenic suspension... Please come... please... vital... The Daleks are... Daleks will conquer, destroy... exterminate--”

Written by Nicholas Briggs, Dalek Empire 3: The Exterminators brings the Daleks' insidious plans for the galaxy to the 67th Century and straight into the path of Earth Agent Galanar (David Tennant). This action-packed space opera features a huge guest cast, including William Gaunt, Steven Elder, Sarah Mowat, Laura Rees and Nicholas Briggs as the Daleks. Download your copy today for just £2.99!
