This was actually my first read-through of this book, despite reading the second one two or three times already. These books are just getting more and more intense and complicated as details from all the series are at play together. 

This book was excellent. It was sad, but also handled so well. While I wish this part of the series didn't exist, it does. To be honest this isn't something I expected which makes it hit all the harder but also really highlights the severity in a way that otherwise just couldn't be captured.  I just hope that Apollo makes the most of their position in the next book.
