The Forbidden Child (Summoner Fan Fiction)

HI!
I don't know what I'm doing here but I thought that there were a distinct lack of Summoner fan fictions about mixed race summoners so I thought I would take the liberty. I've never actually written a book before so this is my first, I'm only 15 so any tips would be much appreciated. I've never good at writing so don't blame me if I ramble in some parts but make sure to tell me so I can fix the chapter. I'll update it as much as I can and don't forget to give me feedback in the comments. After I've finished this one, I might make it into a trilogy, IDK. But send me ideas for other book you would like me to do.

The book follows Kayla, a 15 year old half elf girl who lives with her Aunt Genevieve and Uncle Simon on the outskirts of Corcillum, as she is thrown into a world of summoners and demons, she never thought she would be a part of. Hominum grows restless as Orcish Raids grow bolder and more frequent, some suspect that the escaped Inquisitor Rook has been helping the Orcs in his search for revenge against those who imprisoned him. Can Kayla and her new friends help keep Hominum safe from the Orc whilst dealing with battles of their own? and with enemies around every corner, who can Kayla trust?
