The Kyra Sarin Trilogy - Kyra Sarin

The first three books in the Kyra Sarin series, in one omnibus edition. Kyra Sarin has survived five long years fighting invading aliens on Eris, but can she survive Earth? Facing off against terrorists, the aliens she'd hoped to leave behind, and evil corporations, Kyra has to use everything she learned at war to survive. Inspired by 80s action movies, the Kyra Sarin series is on the lighter side military science.
If you like sweary, over-the-top action, you'll love this series. Grab a copy today, kick back, and watch a space marine show people how it's done.
