War is never easy. For the human Unity League, this is a truth to be stamped on the barrel of every gun and painted on the side of every warship. The Sekar aliens have already killed billions and nobody knows where they came from or how to defeat them. The enemy's only weakness is tharniol - the rarest substance in the known universe. Desperate times call for desperate measures and a shaky truce is made with the treacherous Raggers. The Raggers claim knowledge of data that will assist in the fight. Unfortunately, the data is buried deep in a subsurface facility on a fringe planet called Glesia - a facility which is crawling with Sekar. The mission to recover it goes wrong from the outset, leaving Captain Tanner Conway and his squad the task of rescuing an impossible situation. With limited ammunition and no chance of a resupply, they must fight their way to the mission goal. An alien weapon sweeps through the place at seemingly random intervals. It is Conway's best friend and his worst enemy. Meanwhile, Captain Jake Griffin, alongside Captain Endrax Isental from the Fangrin navy, are left with a similarly unpalatable task - they must handle a Ragger officer with an immensely powerful warship and more faces than a crate full of dice. Hass-Tei-112 has his own plans for what lies below the surface of Glesia. When you can't trust your friends and you can't stop your enemies, what hope is there for survival? Refuge 9 is a fast-paced military sci-fi shooter filled with spaceships, guns, tech and warfare. It follows on from book 4 in the Fire and Rust Series: Death Skies.
