Unite for Literacy
This link is to an American site comprising a selection of books suitable for children in Primary phase, all for free. Each book can be read on screen and there's an audio narration too. You can choose in which language to have the audio narration - the list includes Arabic and Farsi. Note that not all books are available with audio narration in all languages. Note also that some titles may be more accessible by an American audience eg there's a book called "It's Fall" about autumn and another about "ladybugs" where in the UK we'd call them 'ladybirds'.
