I've never read reverse harem before, but I am (was) open to giving it a go.
I was drawn to this story by the gorgeous cover art and the promise of magic school. I love magic school! The atmosphere of academia, the funky lessons, the excuse to make up a lot of fun material, mechanics, and mythos. If you're lucky you get mean girls, illicit explorations and revelations of terrible secrets.
Huh. Anyway.
For my first experience of this genre, "The Spell Traveller Chronicles" fails on all fronts. There is no atmosphere. Like, none at all. From the home of the main character Brianne, we go to school, where basically none of the story takes place. We know of the existence of one teacher. This teacher subsequently pops up in the one scene which takes place in school during her ONE interaction with other students who are not part of her harem. Does the rest of the school exist? Do lessons take place if Brianne doesn't need to dramatically skip them? Brianne, we are told, is a genius; so are members of her harem. Does anything academic take place at all? Anything magical? Why is this set at a magical institute again?
Moving on, let's talk about this harem. As a newcomer to the genre, I was prepared to smile indulgently as fanciful and implausible scenes played out. I was prepared to accept the attractiveness of Brianne. I was even prepared to suspend my disbelief over the romantic tastes of several improbably alluring men. But. This story requires a level of suspended disbelief bordering on the astronomical. Why would anyone be interested in, let alone attracted to, Brianne? In fact, we are given the answer. We are told, several times, that she is clever and kind, interesting and empathetic. But we never SEE a single instance of intelligence or compassion (we are also told she is incredibly strong, unlike the other two instances of character, we actually get to see an example). In contrast, what we are shown is that she is bland, insipid, childish. Unable to make coherent conversation and lacking in any charm or nuance whatsoever. Emphasis is placed on her innocence. Now, innocence is a character trait I can really appreciate. It can work well in every setting and at every level, when done well. Brianne is not innocent, she is moronic. For example, a character mentions being forced to impart intimate favours. "Intimate?" she asks, "like, holding hands?" Yes dear. That was what he meant. And can we get past portraying innocence via stammering, please, Author? In fact, take it out completely, it's clear you haven't a clue what innocence of character means.
The dialogue is inane. The sentence structures uncomplicated. The plot nonexistent. The subject of polyamory is introduced and discussed clumsily. The narrative is in first person; Brianne describes herself as whining and giggling constantly. That mere fact alone should be enough to put anyone off.
That is not to say there is nothing good about this book, however. There was one long scene (of a telephone conversation) near the end which I enjoyed- if not immensely, then at least comparatively much to the rest of the book, and there was one following conversation which promised to reveal depth of character. But you know, it's an unfortunate truth that one scene and one conversation does not a good story make.
