** spoiler alert ** 
 The romance between Riaz and Adria was good, but just ok for me. I think I really like the bonded mate idea, so it was disturbing or disappointing to read about it not working out. 
 I loved the continuing story between Hawke and Sienna! It may be that they stole the show from Riaz and Adria. The overall story arc in this series is incredible, too. 
 I loved the nod in the story to so many questions that I have as a reader. What happens if your soulmate meets and marries someone else? How many different kinds of shifters are there? I was cracking up at the SnowDancers' discussion imagining what kinds of underwater shifters really exist! And Riley and Mercy's pupcubs! 
 Overall a really good book and I can't wait for the next one! So many questions to answer: who did Kaleb finally find? who is the Ghost? what is going to happen to the PsyNet? What is Kaleb's endgame? How many pupcubs will Mercy have?
