All our ebooks can be purchased directly from our website and downloaded immediately from a link in the purchase confirmation email. We publish all of them in two file formats, in ".epub" which can be read on most e-reader devices and for free on numerous web apps, as wellas Kindle-ready .mobi files. (These can also easily be read on non-Kindle devices, using the free and easy-to-download Kindle apps.) When you purchase an ebook here, as soon as your payment has cleared you will be sent an email that contains a "Download file" link that, when clicked, allows you to download your ebook immediately in either format. Contact us if you have problems downloading!
