I don’t know how this wound up on my list but it may have been the cover which has nothing at all to do with the book. The main protagonist is a very nerdy awkward woman who is a “professional fan” (goes to cons, gets paid to write about them etc) who has a friend-of-sort-of-friends get murdered and she and the sort-of-friends try to figure it all out by staging a sort-of con of their own. It’s a little goofy and I did not agree with the cover blurb that it was “laugh out loud” funny, but was definitely the type of story I was in the mood for.
