The first story was not very strong, in my opinion. I hadn't read any of the previous books in the series, so it was hard to connect with all the many characters who were rapidly introduced in scenes that seemed contrived. The lead characters were well-portrayed and the premise was good, but the resolution was too pat. Lucy, and especially her mother, had extremely rapid (and not very believable) turnarounds.
The second story was cute and enjoyable. Not my favorite, but the setting at Fort Kearny was interesting, as were the details about the Pony Express.
I really enjoyed the third story and would give it 5 stars. The characters were so believable and well-drawn, and even the minor supporting characters really came to life. The two lead characters were not the typical hero and heroine, which made the story more fun. Also, I appreciated the writing style and dialog, which seemed true to the era in a way that many historical romances do not.
