Akkad - Book 2

Professor Kessler’s experiment continues, but the powers of his test
subjects are growing at a phenomenal rate. He calls upon Sofi,
herself a guinea pig for him once, and who loathes him, to oversee
the teenagers … and track them down when they inevitably escape. But
are his calculations as good as he thinks? Is it not already too late
to hope to control the five geniuses – or even to stop the invasion,
as the number of enemy incursions suddenly skyrockets?
