Strange things usually happen uncommonly. Once can be a fling, the second a coincidence, the third...not so much.
But for all of it to happen to a group of kids? That is very suspicious indeed.
(I am an amateur writer and English is my second language. So, I am very sorry if you encounter any errors in my novel...Happy reading)
I like it, even if it's only at the prologue. Although the world background needs more editing and the character design is lacking a little bit. Overall, everything's great!
