This isn't quite a five but it is more than a four. You have the description, so need to repeat.
FMC has some baggage from her mother's death, a cold and distant father, and moving around a lot over the last five years. She moves back to her home town and is reunited.
The main character guys are kind of jerks to start off, but not enough to be the bully trope, meaning you aren't screaming at the book when the FMC ends up with them wondering how she has any self-respect never if magic is involved. Don't get me wrong, they are jerks, but in a way that is fitting for a bunch of stupid 16 year olds with their heads up their peaches making 16 year old decisions off of circumstances of others creating. Basically, when they get out of their peaches you can forgive them.
The FMC is also different than most in this trope. She literally has no time for the guys' b.s. or the cliche but required (something the author mocks) catty girl bullies who want the guys. The FMC stands up for herself without being a dog of a witch. She is human, wrestling with some guilt towards the guys' situation, but doesn't let that push her into being walked all over like so many FMC in this genere inevitably and annoyingly do. Still, she is hard on the outside with at least pockets of softness and kindness and vulnerabilities inside which make her likeable.
The guys are okay. There isn't a huge amount given about them. Most of what we learn about them is info dumps of the FMC remembering how they were. There are moments of individual ncharacter development sprinkled in, but not strong enough that after reading the first book you would be able to answer a quiz identifying each guy.
There is an interesting twist, and an underlying mystery that is interesting and add an additional mystery. Nice bomb shell dropped that wasn't blantently apparent. There is the obligatory you need to be trained, but in a nice twist the FMC isn't the character who needs to hit the mat. Also nice, we are spared the mundane pages of training on the mats and complaint of being sore.
The one major complaint is a problem that is common in books like this. The author wants to have characters that are young enough that they are still under the authority of adult and kept in the dark by said adults, but also wants to have a formerly created love. In this case, the FMC left town and the guys when everyone was 11. This results in the now 16 year old FMC talking about how her love life is always x or she always does y in dating and how worrying about how her loves from years ago will respond. You were 11. That were not your loves. Also, you are 16, you don't have a i always do anything in my love life. And this isn't even a universe with fated mates, so the author can't fall back on magic to ease some of that issue. The issue could easily be solved by saying in the magic community they don't mature into their powers until they are 25 or 30 in human years and then you can have 21 year olds who left behind their high school sweethearts and have had a string of not great relationships and now they are back in town for whatever reason. This approach would work particularly well in this series where the school doesn't play a pivital role. There isn't a teacher. All of the school scenes could easily happen at a college or within the community or some magic group like Young Life that all the not of age magic things have to attend.
Also, the climax at the end is a little rushed. I would have liked more of a build up as the involved characters get into the scene. It can literally be build up in the place of the scene with the same jump, (keeping it vague for spoiler avoidance) but more of whomever going to that thing at the place and more of the thoughts as they are going in and it is playing out. I would have liked to have been taken along with the emotions of what was going on more so that i came out of it needing a glass of something strong. It's a good climax, or has the potential if it is a little more flushed, so having that tension and emotion built in would have made the whole thing killer. It's not bad the way it is done, it's just not going to blow any socks off.
Definitely looking forward to book two and already not happy that there doesn't seem to be a book 3, (boo waiting, but also, buy book from series that aren't complete. If you don't you're a monster and are the reason I have series who haven't been completed because the author abandoned them) unless that means the story is completed in two books then yay for getting the whole story but oh no, will that be enough?! Basically I'm hooked and want more.
