Good book. This takes a character from a previous series by the same author and expands the story a little more.
The "Shenandoah Sisters" series was four books, starting with Angels Watching Over Me, set in the time right after the Civil War. The other books were all very good.
I did enjoy this new book as well, which is apparently the beginning of a spinoff series called "Carolina Cousins."
The only thing I didn't like (in Perilous Proposal) was that it rehashed a lot of stuff from the books I'd already read. But I guess that's unavoidable.
