A Kiss in the Snow is Susan Mallery´s latest addition to the Fools' Gold Series but it's not, in my opinion, one of her best. It's a novella, so pretty short, and as such you cannot expect deeply developed characters and a complicated plot. Although I'm not a huge fan of these short stories, I understand that point.
My problem in this case is that the plot - what little there is - just doesn't make sense to me. What intelligent woman, after being abandoned three times by her boyfriend (the last time right at the altar) would be willing to give the man a fourth chance, no matter how many times he says he's changed? Actually, if it happened to me and said man showed up in the town I grew up in looking for me (that's not exactly how it happens in the book, but the end result is the same), I would take him more for a stalker than the love of my life.
Even though A Kiss in the Snow can be read as a stand alone book, I wouldn't actively recommend it unless you really, really love the series. Otherwise there are much better books by Susan Mallery you can read instead.
