Raissa Luara de Oliveira has amassed a collection of 18,000 books inside a small tin-roof room at a local community centre for her new library called 'Lua's World'.

The library is a cozy space lined with pillows, and immaculately packed with books.

"At 12, I've done more for my neighbourhood than you've done in your whole term," she recently told Rio's mayor, the far-right evangelical pastor Marcelo Crivella, in a defiant video she posted online.

The idea for the library was born six months ago, when Oliveira was at a book fair.
"I saw a mom telling her daughter she couldn't afford to buy her a book for three reals," she says.
"I said to myself, 'You have to do something.'"

Surreptitiously using her grandmother's cell phone, she sent out a Facebook post asking for book donations.
Then, pretending to be her grandmother, she sent a message to the vice-president of the local community association, asking her to give her a space to create a library.
The woman, Vania Ribeiro, guessed right away it was Oliveira. But she agreed to the plan.

Oliveira's bubbly video message went viral, leading to invitations to appear on a string of TV programmes.
Her project is so successful it has been receiving around 1,500 books a week, way more than her small library can hold.
Behind the shelves, she has boxes full of books she wants to donate to similar projects elsewhere in Rio and in Brazil's poor Northeast.
