Book 1

The Roar

by Emma Clayton

Published 7 July 2008
Twelve-year old twins, Mika and Ellie, live in a future behind a
wall - safe from the plague animals beyond. Or so they've been told.

But when one of them disappears, and the other takes part in a sinister
virtual reality game, they begin to discover their concrete
world is built on lies. As they go in search of the truth, and
a strange sound in their heads grows to a roar, they find out that
children and the planet have never mattered more.

Book 2

Mika and Ellie have the ability to hear thoughts. Their mission:
listening in on the mind of evil Mal Gorman, who's determined to
use an age-resisting serum to stay forever young. Forced to play
along with his plans, the telepathic twins may be the only people
able to release his brainwashed army of children.
That's when they begin to hear
The Whisper, which tells them they should be fighting fire with
fire. This could mean revolution . or war.
