Book number one of a one book paranormal romance dark fantasy series that is a spinoff from the ten book Kate Daniels series by the author. There are several short stories and followon books to the Kate Daniels series.  I read the well printed and well bound POD (print on demand) novella trade paperback published by NYLA Publishing in 2015 that I bought new on Amazon recently.  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.
Derek Gaunt and Julie Lennart-Olsen have been called to a home and found the family murdered.  The family had a unique object that they were safe keeping and the thieves murdered them for it.  Derek and JUlie set off to find the thieves and murderers.
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.
