So I decided to read this before reading the first book in The Summoner series The Novice, and I loved it!
Arcturus is sassy, amazing and his relationship with his demon Sacharissa is heart warming and at one point had me smiling so much I hurt my jaw.
The story was great and wet my appetite for The Novice, I feel that reading the prequel first gave me a lot of information that will be great to know before starting the series (even though they will most likely explain it in the books). The explanations for mana and even some demon species has gotten me really excited to start this series!

I would definitely recommend this to anyone who loves fantasy!
now off I go to read The Novice, I really hope Arcturus appears in the main story! :)
