This was one of those "ooh, that sounds like a short, fun, kinky story" sorts of books that I buy on a lark every once in a while. Most of them I don't end up liking very much, but this one was different.
The two main characters were nicely well-developed and believable. And with their personalities, it was also believable how they could have worked at the same company for years and not have either persued or nixed the idea of a romantic/sexual relationship.
The unique and creative use of twinkle lights and tinsle also deserve a mention. Great fun there.
