Devik

Shades of gray meets black and white and results in color.
Thirty years ago, the Zuvgran released a virus that killed most Svesti females and rendered the remainder infertile. The Svesti initiate first contact with Earth when their scientists discover that humans and Svesti can interbreed. Humans may be able to save the warrior species that has been protecting Earth's region of space for a century.

Emmy is just trying to stay out of jail. She's been ordered to hack Svesti technology and bring back everything and anything that will advance her country's plans. She pushes limits to push people away.
Devik is intelligent, strong and sexy with an unshakable foundation of right and wrong. He's also the head security officer on the space cruiser.
Devik is the second book in the Svesti Fated Mates series with a HEA and can be read as a standalone, although it is recommended that the books be read in order for the best experience.
