Lawfully Matched by Lorana Hoopes

This one played out like I thought mail-order bride might happen. She ends up with a robber and murderer. She escapes and finds a lawman to help her. He marries her for convenience, but of course they fall in love. This story is well-written and has lots of action. Despite her running from the man who sent for her, our heroine is brave and has a lot of gumption, more woman than our hero is used to.
