This was a great filler book before the start of the new spin-off series. I really loved getting to see the extra thought that went into some of the characters that were actually in the series for only a page or two! There is a ton of world building that went on here...

The character profiles were fun. I loved seeing the list of the famous Cahills in each branch. I liked finding out where each of their strongholds are, and what their secret weapons might be. All in all a fun book to flip through before I read the first Cahills vs. Vespers book!
