I read some English from children's' books at first. "BOY",and "GOING SOLO" by Roald Dahl, witer of Charies choclate factory.
and detective story " SHRINK RAP" by Robert Parker, and
"Message in a bottle" by Nicholas Sparks ,It's a love story became a movie.
"Flowers for Algernon" by Daniel Keyes.
"The kite runner" by Khaled Hosseini
"Dancing on the Bridge of Avignon." by Ida vos.
They all written in simple words but very beautiful story. They are very famous so, you can find them at the library, I think.
I'm learning English. And I'm reading "The Alchemist"
It's very interesting :)
I think Harry Potter is a good book to read in a foreign language, because JK Rowling writes with a great amount of vocabulary and detail.
The books available in many different languages, so you can read the foreign language book, and look up the meaning in your native language book!
