I liked the first three stories. I'm very familiar with Larissa Ione's LOD series and her Demonica books so Fight Club was really nice to revisit that world. (4 stars) 
 Guardians of Eternity was new to me. I knew there was some back story I was missing but the short didn't leave me totally clueless. I enjoyed it and will probably look up the series in full when my TBR pile gets a bit smaller. (4 stars) 
 Nightwalkers was new fer me too and I did enjoy it. I'll probably look this series up too. (3.5 stars) 
 I honestly couldn't get into Dragon Kin and stopped about an hour into the story. Just wasn't my cup of tea. (DNF) 
 The audiobook was narrated by Justine Eyre, and we have a love hate relationship. I always hate her voice at the beginning of a book because she has a whiney quality to her voice, but once I get over the shock of hearing her I focus on the story and she doesn't bother me as much. (3 stars) 
 I usually don't go for anthologies, but with the exception of the last story I wasn't disappointed.
