"Dead Collections" by Isaac Fellman is a gem of a book.  Beautifully written, full of wry humor and sweetness, and with a main character who you will totally recognize.  Sol Katz is a geeky neurotic trans Jewish vampire who is crashing on the DL in his San Francisco office where he works as an archivist.  He meets a widow who has come to donate her famous wife's papers.  Weird (weirder?) shit starts happening.  This book is in many ways more vibes than plot, but SUCH VIBES.  I will definitely be regularly re-reading this one.  It is aimed at adults, mostly because it will go over younger folk's heads.
