Duquesa by Default — Maura McGiveny

But she found she was marrying for love

Joanna was very relieved that Duque Rafael de Santiago was able to help her out of the embarrassing mess she'd got herself into--but there were limits to her gratitude!

She would not marry his younger brother, Manuel! The bizarre situation soon got completely out of hand, for Manuel tricked them both and publicly announced Joanna's engagement to Rafael.

What drove these brothers? They didn't consider Joanna's feelings at all!

Hero: Duque Rafael de Santiago
