Mikolaus by Margo Bond Collins

They’ll change her life. She’ll change their world. The days of pitched battles to win the hand of one of Lurra’s very few women may be over, but as the top fighters in the ceremonial, gladiator-style games, Mikolaus always assumed that he and his triad—including his triad-brothers Domiku and Luken—would settle down with a traditional Lurran girl. Until the day he meets Hannah. She’s eager enough to learn about Lurra, but despite her attraction to the culture and Mikolaus, he’s not sure he can get her to reconcile her Earth-2 upbringing with Lurra’s strict ideas about marriage.Not alone, anyway.Maybe together, his triad can convince her that marriage should be between one woman … and three men.
