What's the Name of That Book??? discussion

This is a sheikh novel. The heroine thinks that the sheikh would have gotten her sister pregnant and then left her. So she deliberately joins his company and confronts him. Then it is revealed that it is actually his brother who was responsible. The sheikh takes the heroine to his kingdom and keeps her there. I think the pregnant sisters name is Cassandra. I just can't remember the author or the title of the book.

Clare Connelly's The Sheikh's Virgin Hostage

Shine, what's the genre? Genre always needs to be in your header.

A novel about a sheikh could be romance, horror, mystery, literary fiction, historical fiction, sci-fi, fantasy, manga, Christian fiction, erotica, Christian cozy, cozy mystery, sci-fi cozy, sci-fi hard, Christian erotica, Christian sci-fi, or chick lit.

Hi I think it may be Elizabeth Lennox's book.
It may be Friendship series but FMCs are friends. (Sheikhs present)
Or The Hart Sisters trilogy, FMCs are sisters. (No sheikh)
Or some of her standalones too.
