Alexa's Web (Mastering Holly Oaks #3)
Rayna Stone

James Gainer and Ryan Stromfield are a committed D/s couple who have almost given up hope of finding a third, until Alexa moves to town. She’s everything they want, but gaining her trust and handling the problems a triad faces in a vanilla society may be more than any relationship can stand.
Alexa must choose between her job and its security at the university, and her relationship. All while trying not to become a new victim from past sins.
