The Cly — Sean Monaghan

Tony Brock saved humanity once. But in the mess, he lost his relationship with his daughter. Now the Cly pose a new threat. A threat that might destroy the Earth itself. And the aliens won't negotiate. So Brock's back in the thick of it. Chasing them down, and chasing the faint hope of seeing Bex one more time. An alien invasion novel with a difference.
