The story is actually doing somewhat better than Helena Puumala's "A Christmas Miracle at the Lake" did, in terms of sales and downloads, at the same time (i.e. after the first day). Ranking wise, It's been mostly in the low teens for "genre fiction>family life", on Amazon.com and uk, so far.
Christmas Miracle really took off in the last day or two of its promotion, as did Summer Camp Mystery, over the Labour Day weekend. Both of those hit number 1 in some key categories. So, you never can tell what will happen. That's what makes it fun, a bit like betting on the horses. :)
