Research confirms that extensive reading is one of the most effective ways to build vocabulary and improve fluency. Graded readers match text difficulty to your CEFR level, so every page is challenging enough to learn from but easy enough to enjoy. Each book includes a dictionary beside the text, chapter exercises, and online vocabulary practice — everything you need in one package.
Formats: e-book, paperback and super audiobook
Our graded readers come in several formats. The text, the CEFR level and the glossary are the same in each — only the way you read changes. Pick whatever suits your day: the e-book on your phone on the way to work, paper and pencil at your desk, or the super audiobook when you want to read and listen at the same time.
E-book (EPUB and PDF). You can download both files right after purchase and read on an e-reader, phone, tablet or computer. Difficult words have their translation in a pop-up note: one tap and you are back in the story, no dictionary needed. Each chapter ends with vocabulary exercises, and a link takes you to free online practice with the same words.
Paperback. A classic softcover book, printed to order and sent by post. The glossary sits in the margin, right next to the word it explains, so you never have to flip pages. Chapters end with crosswords and vocabulary exercises, and QR codes take you to online practice on your phone. A good choice if you like writing in your books or want a break from screens.

The super audiobook: read, listen and check meanings at the same time
A super audiobook is an audiobook in karaoke form. A narrator reads the book aloud while the same text is in front of you, with a marker moving along it word by word. You always know which word you are hearing, so you never lose your place — even when the narrator speaks faster than you read. Your ears tell your eyes how a written word sounds, your eyes tell your ears how to spell what you hear, and both routes reinforce the same words at once.
The real difference shows when you meet a word you don't know. In an ordinary audiobook it is gone in a second; in a super audiobook it stays within reach: glossary words are marked in colour, and pressing and holding one shows its translation in your language. You check the meaning, keep listening and never lose the thread. A slider sets the narrator's speed from 0.5× to 1.5× — slow down at first to catch every syllable, then speed up towards natural speech. The words you meet while reading come back later in short exercises in the app, such as a mini crossword or building a word from its letters.
Reading while listening is well supported by research. In a Canadian programme described by Lightbown and colleagues (2002), children who for three years learned English only this way — reading books while listening to their recordings — understood the language as well as or better than peers taught in regular classes. Waring and Takaki (2003) showed that you need to meet a word at least eight times to have even a 50% chance of recognising it three months later. Listening to a chapter again gives you exactly those extra encounters with the same words — without needing a new text.
At A1 and A2 the super audiobook helps you connect spelling with pronunciation — especially valuable in languages that are not read the way they are written, or that use a different alphabet. At B1 and B2 it carries you along at the pace of real speech, so you get used to fluent listening and stop pausing at every sentence. Advanced readers often don't need a narrator at all — which is why you decide when to switch it on and when to read silently.
The super audiobook plays in the Pentecost app or in your browser, on a phone, tablet or computer. You can add it to an e-book: on the book page, tick “Add the audiobook” in the e-book box; if you already own the e-book, you can buy the recording on its own. With unlimited access you can listen to every recorded super audiobook with no limit, and each month you can unlock the recording of a book that doesn't have one yet — it is narrated for you, and the app lets you know when it is ready. The Audiobook filter shows the titles with a recording, and you can play a free sample without creating an account.
