Blood of Gods - Simon A. G. Spencer - Bog

Across the galaxy, mysteries deepen and threats increase.
On Utopia, home of the peacekeeping Rashani, anti-neutrality protests teeter on the brink of riots. On the outskirts of the galaxy, the Sun God finds a derelict spaceship that somehow crossed the supposedly-impenetrable Firmament, its purpose still unknown. And on a storm-wracked jungle world, the first battle of a war between the main galactic powers approaches.
Marissa Rhapsody, half-Deus gladiator, has recovered from battle only to be targeted by mysterious assassins. She accompanies a diplomatic mission to escape from her pursuers, but a potential war zone is a poor place to find safety.
The Bythos Empire is fast approaching to conquer the primitive world of Tashwa. The diplomats desperately trying to sway the fearsome and secretive Kunalim are about to get caught in the middle of the biggest firefight in the galaxy in centuries.
