Shadows of the Void Books 1 - 10

Kickass sci-fi heroine versus deadly aliens. Growing up as a Martian on Earth has left Jas Harrington solitary, quick-tempered, and with zero tolerance for fools. All plus points when working as chief security officer aboard prospecting starships. Jas' latest berth is aboard the Galathea, which trawls the reaches of the galaxy seeking precious minerals and rare resources. She thinks it's a routine trip.
She's wrong. An inspection of a far-flung planet leaves Jas suspicious that there's more to the place than meets the eye. If only she could convince the captain of the need for caution, but she might as well wish for a tasty meal in the ship's canteen. All hell breaks loose, and Jas's skills are put to the ultimate test. Can she enlist the help of the only two friends she has? She's in a race against time to prevent hostile aliens from achieving their goal.
If she fails, the ship's crew, the galactic empire, and humanity itself are at risk. Shadows of the Void is a fast-paced, action-packed space opera. Complete series.
