Book number one of a one novella book dark fantasy paranormal romance series.  The series is a spinoff to the Kate Daniels series.  I read the well printed and well bound POD (print on demand) trade paperback published by Nancy Yost Literary Agency, Inc in 2024.  I look forward to future novels in the main series and this spinoff series.  Note that “Ilona Andrews” is the pseudonym for a husband and wife writing team.
Kate Daniels's universe sucks.  Forty years ago, the tech world crashed over the entire Earth and was replaced by the magic world in the form of a magic flare.  Guns don't work, cars don't work, electricity and phones do not work.  But magic works.  Good magic and bad magic.
After a week, the tech world came back to a drastically changed world. And radically fewer humans.  And the magic world came back after a while.  And the tech world came back after that.  And so on and so forth.  Each world can last a few weeks or a few hours.
Roman is the local Volhv wizard in Atlanta serving Chernobog, the god of Destruction, Darkness and Death.  He has worked a deal with his god that he gets December 23 to December 25 off each year.  And his crew of very strange animals has drunk all of his eggnog and eaten all of his cookies during the night.  And a 15 year old kid has passed out in his front yard with a knife wound in his thigh, asking for sanctuary.  And mercenaries are chasing the kid with a powerful wizard.
I liked everything about the story.  I especially liked the very clear distinction between the tech time and the magic time.  I had never thought about it that way.  The series may be inspired by "Ariel" by Steven Boyett and "Dies The Fire" by S. M. Stirling except those never interchange the tech time and the magic time, they just transitioned to the magic time and never went back.
