I don't know why I waited so long to read this series. I did enjoy Nalini Singh's writing in the Guild Hunter series. I think this series' description always looked too confusing to me. 
 When I started reading it, it wasn't confusing at all, it made perfect sense. Just like in the Guild Hunter series the world building in this book is wonderfully imaginative. It takes place in year 2079 in what is an alternative universe, where there are not just humans but also the race of Psy, whose minds are very advanced but they are emotionless, and the race of changelings, who are basically were-wolfs, were-leopards etc. 
 The story of this book is a classic romance of a Psy woman who is flawed because she can feel. She meets a changeling man in business capacity. Worlds collide, murderous plots are revealed, hot stuff happens. 
 I'd say this is a must read for all paranormal romance readers and I'm looking forward to book 2.
