It isn't easy to be Katie Weaver. Her sister-in-law Ella is about to have a baby, making Katie an aunt for the second time . . . and she's only six and a half! Plus, her favorite librarian, Miss Donovan, seems sad. She won't even fix up the rundown nativity in front of the library in time for Christmas. Then, an old woman is attacked outside the library, and, one by one, the nativity figures start to disappear!

Luckily, there's a new deputy in town, Connor Fields.

He takes a real liking to Miss Donovan . . . and he promises to find the missing nativity pieces for Katie.

Now, all Katie has to do is pray that Ella's delivery goes well and that some kind of nativity is in place for Christmas Eve. Oh, and that Miss D. falls in love with Connor. Katie knows from watching her three brothers that it makes people real happy. And that would be a Christmas miracle indeed!
