Alcatraz vs. The Evil Librarians. Book 1. Talent Undercover

Alcatraz did not remember his parents, but they must have been extraordinary people: one needs to have a special sense of humor to name their child after the most sinister prison in the entire history of the United States. And... on his thirteenth birthday, Alcatraz realized that his parents were also cruel people. After all, he received in the mail the only inheritance they left him - a bag of sand! Fortunately, his grandfather - a powerful wizard, the Great Oculator, who possesses a rare family talent and knows how to use the wonderful properties of lenses - came to congratulate Alcatraz and get to know him. Now Alcatraz, together with his grandfather, will have to find out what kind of lens can be made from the sand and at the same time save humanity from the evil Librarians' conspiracy.
