Malachite eyes.

Lucas, an extremely perceptive and cautious autistic boy, had only one goal for his final year at this boarding school: to graduate and go unnoticed.

There was only one problem: his fraternal twin brother, Luiz, an impulsive and troubled boy who had look to attract trouble like a magnet.

And, to his misfortune, his plan crumbled before the end of the first Exam semester. After the senior year party, the focus of his life no longer revolved around teen drama or autistic problems...

There was a corpse in the Lake.

At Coronel Santa Trindade boarding school, Lucas learned that sometimes, drawing attention is the least of his problems.
