House of the Scorpion by Nancy Farmer, Raz

I'm reading House of the Scorpion, by Nancy Farmer - an extremely interesting book. It's the tale of Matteo Alacran, a clone of drug lord El Patron, who is the ruler of Opium, a country that has replaced Mexico.
Matt grows up in a shack in a vast land of opium farms, and is completely cut off from the outside world. The only other person he knows is Celia, his caretaker who loves him. One day when three kids walk by his window, he gets their attention and breaks out of the house. He comes to the Alacran estate, a completely different world. He is launched into adventures, at first imprisoned, and then being freed, finding secret passageways (not saying any more), and many exciting things happen.
I am at the part where El Patron is poisoned by Celia and dies, and Tam Lin (Matt's teacher and friend) helps Matt escape the Alacran empire and flees to Aztlan. I am reading more right after this post!
