SYNERGIAN: A Divided World

(1st book of the "Synergian" series)
(inspired by the books "Shatter Me" and "Divergent *series*, with a small bit of Harry Potter)

What if there had been a world with people divided into specific groups? A world in which peace is the ultimate aim of the people?

The Law Of Group declares that every teenager of eighteen years old is to pass a test which declares the group best for them. They are respectfully;
The Veritas, the honest and law-full,
The Nexus, the intelligent and creative,
The Edenites, the peaceful and loving,
The Wardens, the brave and protectors.

Except these four groups, the ones who do not pass their tests, ones who's minds don't find interest in any of the categories are considered as The Groupless.
But, opposite to The Groupless, the ones who find interest in a number of things, and have most traits of all the four groups, are considered a threat to the society due to their power, which is unknown at present- The Synergians

Tristana Vale, born in a family of The Edenites, who got her test passed- but as a Synergian, who kept her group a secret and hid under the mask of being a Warden.
