World's Collide

Unlike her triplets Cedar North is a troubled teen with a twin soul, and a past of theft, arson and murder.
After four years in the most world renowned detention centre the Eonian.

The Cryptid's council and Homo sapiens prime minister has come to an agreement that Cedar North and a few other students are to go live in the Human City Albion for the year and do the Eleventh grade at the school mountain view high.

There Cedar meets the chaos club, a group of friends who annoyed the principal enough to make their own club befriends the young werewolf. As the havoc filled year goes by Cedar and the rest start uncovering truths their governments had tried to hide away.

(Summary is a work in progress)

There is some topics like abuse, murder, bit of swearing, etc. And tons of angst so don't read if it negatively affects your mental health or your uncomfortable with heavy/upsetting topics

I would advise only teens and up read but it's up to you
I'm not making it mature since there's nothing that I feel would make it 18+.

I'm going to say that it would be in the YA section if it was published.
