After completing your purchase, you'll receive an email with download links. You can also access your purchases anytime by logging into your account and visiting your order history. Downloads are available in EPUB and PDF formats.

Our ebooks work on virtually any device - Kindle, iPad, iPhone, Android phones and tablets, Mac, PC, and dedicated e-readers that support EPUB format. EPUB files work with Apple Books, Google Play Books, and most reading apps. PDF works everywhere.

You can email EPUB or PDF files directly to your Kindle's email address (found in your Amazon account settings), or use the Send to Kindle app on your computer. Amazon will automatically convert the file for your device.

Due to the digital nature of ebooks, we generally cannot offer refunds once the files have been downloaded. However, if you experience technical issues or received the wrong product, please contact us and we'll make it right.

Bundles include multiple ebooks at a discounted price. Each book in the bundle is delivered as a separate file, so you can read them in any order. Bundle descriptions list exactly which books are included.

Currently we only sell ebooks directly through this store. Print editions of many titles are available on Amazon.
