I have enjoyed a couple of other books by Claire Contreras so was interested to listen to this series.  The plot was engaging and well-paced, keeping my interest throughout. The spice level was present but not as intense as other books I have listened too. 
The characters were interesting and well-developed, and I enjoyed the perfect balance of character development and an intriguing storyline.
I felt the ending a little rushed, but am interested to hear where this series goes. No cliffhanger.
