Book number one of a one book dark fantasy series.  This book is a spinoff of the very successful ten book Kate Daniels series.  I read the well printed and well bound MMPB published by Ace in 2012.  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.  The book also includes a free 108 page Novella in the back called "Magic Gifts".
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.
Andrea Nash is having a bad year.  She was outed as a hyena shapeshifter when Kate Daniels aunt attacked Atlanta and Andrea changed in public. Then the Order of Knights threw her out of the Order.  Now the Pack wants her to join or leave Atlanta.  And she just broke up with her boyfriend, alpha of the Bouda clan of the Pack.  Not quite the Hallmark movie.  Maybe a really dark Hallmark movie.
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.
