Grulen by Wavy Martin

Former slave meets recovering amnesiac and new memories are made.

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.
Morgan can’t catch a break. Kidnapped and forced into slavery by aliens, rescued, then she was kidnapped again and experimented on by the Zuvgran. She’s not looking for love, just some peace to recover.
Grulen suffers from amnesia. He knows he has an important mission, but he can’t remember what it is.

Grulen is the seventh 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.
