The Prince's Bride-To-Be - Carramer Crown 2 (Harlequin comics)

As a favor to her twin sister, Eleanor, Caroline poses as her when summoned to fulfill a betrothal that was arranged when they were children. Caroline did as her sister asked to help Eleanor be with the man she truly wants to marry, but mostly Caroline just really wanted to see Eleanor’s betrothed, Michel de Marigny, again. She feels conflicted about having to lie to the man she loves, and then she feels even worse when he tells her he wants a loveless marriage. Now Caroline must hide her identity and her love from Michel if she want to stay with him. But how long can this charade last?
