 This book is the first in this series; however, the author wrote a previous series set in the set universe with the same characters. As I didn't know this when I started reading, I was very confused about the relationship between the characters, as they were only explained superficially and several chapters in the novel. It's also the same with their age. 
 The guild and its members are interesting, but, just as with the characters, I felt that they are not introduced with enough details to well understand what and who they are. The author really tried to avoid info dumps and summary of the previous books and to introduce information along the way, but unfortunately I don't feel that it was balance well enough. It's also the same for the plot; however, if you just read through the first few chapters (they are rather short), it gets better. 
 The story is written from the POV of Kyth and Ellah. However, I felt that the POV changes far too often: each time I was started to get use to a POV and to get into what was happening to the character, it changed. It was very annoying and frustrating; I would have preferred the author to write longer chapter in the same POV and to only change it when it felt natural in the narration. 
 This novel is heavy on the romance side: Kyth and Ellah are adolescents and are apparently in love for the first time, so there is a lot of admiring and sighing over their love interests and being confused because of a smile etc. You have to know what you are getting into or it may soon become exasperating. Even knowing it, I felt it was just too much as it contributed with the too frequent change of POV to slow the story. 
 Another point that should be mentioned is that the guild members have some kind of superpower for fighting in the same spirit as manga characters. They are inhumanly fast and strong, can just survive any kind of injuries and can single-handedly defeat a dozen of opponents. 
 The plot was interesting if a little predictable, but I didn't really managed to get into the story because of the elements I mentioned and I just lost interest midway.
