#37 Unperfect Souls by Mark Del Franco

 A word of advice don't read this one unless you have read the other books first since it continues to build on the previous books and reading in order explains the background info better than just the bits you get from the small info that gets sprinkled in the current book. This one sheds more light on the mass in Connor's head and he doesn't care for some of the implications and also gives info on Leo's background as well. The plus is that I at least have the next book all ready in my stack ready to read.
