2044: The world is steeped in a planet-annihilating global war. The only way to save it is to travel backward in time. Bewildered maths teacher Murdo Ironside is recruited to join the League of Kairos, a secret agency for those few who possess the Time Gene, which confers the ability to turn back time.But their powers are limited. They must join forces with other Time Travellers from the past, and build a network of chronomotives - trains running through time - and search for a super-powerful time-traveller from the 1990s, known as the Anchor.But the Anchor is angst-ridden schoolgirl Roxy Malone, who is terrified of the power she cannot understand nor control. Can the League find her before the Time Gene itself kills her?Or before she falls prey to Dark Forces from across time who want her dead?
