Alien Hunter by Sue Mercury

When a huge Vaxxlian warrior named Zann offers to protect former Ambassador Sasha Embers and help clear her name, she hastily accepts his help—even though doing so means she must become his forever. She doesn’t plan on falling in love, but the darkly mysterious warrior’s kisses make her melt and his touch ignites a firestorm of longing within her.
