Thanks to Books Forward PR for the free advance copy of this book. 

Rachel is a human from a different dimension. She travels to ours for her job as a daemon collector - picking up malfunctioning daemons (invisible creatures that tempt humans to steal, kiss, riot, etc.) for repair. Today, though, she's been assigned the job of tracking down a dangerous person who is trying to break the barriers between dimensions, and everything goes haywire. 

Wow, what a fun book! I loved the world built here, it's so clever and unique, and shown to us so clearly in just barely 200 pages. Rachel is a fantastic character - sharp and prickly, but with a good heart. GATEKEEPER also touches on a number of social issues, ranging from women not being taken seriously at work to the difficulty Black Americans have tracing their ancestry due to slavery.

I'm looking forward to seeing how this universe expands in the next book, since there’s obviously more coming with the way it ended. Also, I hope there's more of the daemon who likes to wear a coat, it was so cute!
