Noooooo, another semi cliffhanger ending. This book resolved the immediate issue but not the overall problem. Now I have to wait for the third and final installment for this series. 
 I was completely enthralled by A Strange Hymn and didn't want to put it down. I loved Des and Callie together and really liked that Temper was able to be a part of this book as well. She is a badass chick and I think she would be a good character to use in a spin off series. I like that I don't really have a clue where the story will go from here or who the Thief of Souls truly is. Hopefully I won't have to wait too long for book 3 to be released so I can finish this series.
