Audio Book:

You can now download the audio book for Lost & Found, which was created using purchased voices through Future anthologies will utilize Amazon Polly voices. Please note that the audio books are generated using text-to-speech technology (as opposed to a real person reading), so the pronunciation of some words is not perfect. However, the quality is still very good—unlike the computerized voices of years past—and provides a new way for our readers to enjoy the series.
