Described as "a collection of short stories told from a different character's involvement and point of view," this is actually a linnear novella in which the POV changes from chapter to chapter. None of it was particularly great. Just a very surface description of some bloody conflict between the seelie and unseelie courts during a fancy ball, with almost no background, engaging characterizations, or engaging dialogue.
I acquired this some months ago, and in the meantime Farrell has released a novel based on it, entitled Soul. I believe it was only after the publication of Soul that this shorter work began to be listed as a "Prequel companion", and it's not exactly that, as the events described in it mirror events that take place in Soul.
In my opinion, having now read two novels and two "short story collections" (one of which actually was a short story collection!) by Farrell, as well as the first chapter of Soul, perhaps Farrell should stick to novels. The longer format provides the obviously-needed room to develop interesting characters. One Night with the Fae lacks in this area, and pretty much reads like an author's outline for a longer work.
