Cora Seton, Issued to the Bride, (books 1-4)

Adorable series that begins, improbably, with a scene from Pearl Buck’s The Good Earth — a seraglio of men sitting looking at a series of photos or paintings of women who are too beautiful to be real. But they are real. And they have a price.

In this case, the women all belong to a General; they are his daughters, and the men who have been looking at their photographs for months are waiting for their next mission. They don’t realize that the daughters are their mission.
