Bane by Bex McLynn

They call him the Bane. She calls him her hero.
Maude never considered herself weak-minded, not until she woke up hearing a voice inside her head. Now she’s dealing with alien captors, a bio-mechanical organism infecting her body, and two brutal suns frying her skin. Oh, and time is not on her side. Her sole ally is a towering Teras alien who steals her breath with his brilliant smiles and heated gazes. She desperately needs to get home, yet her savior is stealing her heart.
Therion Borac is many things. His mother’s darling. His father’s hellion. His house’s bane. Never an honorable man. When his house calls upon him to rescue an abducted human woman, he’ll eagerly save the lady but won’t hope for anything more. With crime lords and powerful Teras organizations threatening Maude, he knows she’ll need a scoundrel at her back more than she’ll need an honorable man at her side. For Maude, he will gladly remain the Bane.
