Horizon Storms (The Saga of Seven Suns, 3)

Caught in the middle of a titanic struggle between two alien superpowers, the factions of humanity and their allies, the Ildirans, are under siege. Can they resolve their differences to fight a common threat?

As old intrigues and dark secrets come to light, a man who is believed to be long dead returns with an ally who may save mankind. But this new fragile hope will be threatened by a fresh betrayal - the most bitter and brutal of them all...
