Follow your audiobook's narrator in the text, word by word, then pick up reading where you left off. READ AND LISTEN TOGETHER Add your audiobook to its matching ebook. Unison Reader aligns the narration with the text on your device, so you can listen, read along, or switch between the two without hunting for your place. START WITH WHAT YOU HAVE Only have the ebook?
