Booklist: There are three things to remember about the spirit realm: follow the rules, get consent, and do not eat or drink. Another unspoken guideline is to trust no one beyond the border between the mortal and spirit worlds. Controlling each domain is a god or demon who will kill for sport, especially anyone who breaks their rules. The border keeper has had many names and inhabited untold vessels over innumerable years, but she lives alone and does not suffer fools lightly. She once loved a god king but lost him to treachery and murder centuries ago. A wandering scholar arrives at her home, seeking passage, though he will not specify what he is looking for in the world of spirits. He has a sad story that brought him to her door, and for reasons she does not understand, will compel the guardian to accept him and act as his guide. With parallels to a range of mythologies, Hall’s elegant descriptive language evokes a vivid world of lost souls and revenge in this fast-paced fantasy debut.
