Our audiobook titles are currently exclusively distributed digitally via Audible to Amazon and other audiobook networks.

Ebooks are currently available via Amazon Kindle, iTunes, Kobo, Barnes & Noble and other major e-tailers.

It is also possible to arrange sponsored versions of some of our products. For example,  The Encrypted Pocketbook of Passwords is an item most people keep close at hand.
