Universe on Fire Books in Order

Decades after alien conquerors barred humanity from space, scientists secretly open a portal to a universe of magic. Combining that discovery with technology gives Earth a possible weapon against its rulers and the chance to reclaim its future.

Seeking an advantage against technologically superior enemies, Captain Kane Reinhart leads an expedition through a portal to a magical version of Earth. A genetically engineered soldier serving alongside him conceals their biological connection while facing the unfamiliar world’s dangers.

Earth has secured a fragile peace, but rival powers threaten its independence and covet its magical technology. A mission to recover ancient discoveries may provide another advantage, even as the return of an old enemy endangers the wider galaxy.

With its allies struggling against invasion, humanity sends a newly equipped carrier to locate the enemy’s home system. The mission must cross dangerous remnants of an ancient empire before the opposing fleets can turn their attention toward Earth.
