Crown of Chaos
by Aaron Hodges
Meanwhile, King Braidon has earned a victory against his treacherous wife and her zealous Knights. If only the war could be so easily won. Marianne still holds the capital, and has magic enough to conquer the Three Nations. Braidon must gather the forces of good beneath his banner, and fast, before the queen can march on his stronghold.
Arch Allies
by Audrey Sharpe
For pilot Natasha Orlov, a starship buried in a sea of sand is her ticket to freedom and independence. Sure, restoring the ship won’t be easy, especially when the Feds figure out she’s running an illegal salvage operation, but she’s never shied away from hard work. Or challenges. Good thing, too. Because she’s on a collision course with her competition.
Lost Mission (Oblivion Book 1)
by Joshua James & Daniel Young
Two decades of bitter war between Earth and her furthest colonies is finally at an end. Captain Lee Saito’s massive new starship is sent to seal the uneasy truce.
But a series of terrorist attacks on Earth and the mysterious acts of a strange cult threaten to derail the fragile peace.
When the mission goes awry, Saito must try to salvage what he can in deep space while his estranged son must navigate a conspiracy back on Earth that could implicate the highest levels of government.
But conspiracies go both ways and no one is as innocent as they might seem.
As it all spirals out of control, the future of humanity hangs in the balance.
Lost Mission, the first book in the Oblivion series, is a high-octane, action-packed blast that will leave military science fiction fans hungry for more!
