August Pullman has been home-schooled all his life. Now he is starting fifth grade at a New York City middle school. He doesn't want to draw attention to himself, but that isn't easy when he looks like he does.

Penguin Readers is a series of the best new fiction, essential non-fiction and popular classics written for learners of English as a foreign language. Beautifully illustrated and carefully adapted, the series introduces language learners around the world to the bestselling authors and most compelling content from Penguin Random House. The eight levels of Penguin Readers follow the Common European Framework and include language activities that help readers to develop key skills.

Wonder, a Level 3 Reader, is A2 in the CEFR framework. The text is made up of sentences with up to three clauses, introducing first conditional, past continuous and present perfect simple for general experience. It is well supported by illustrations, which appear on most pages.
