Slowly but surely (with emphasis on the slowly, as it's a lot of work!) my catalogue is going up on Google Play as auto-narrated audiobooks. This means they're read by an AI. The first book in each series is free, so you can check them out before you buy. They're available here.
In case you're wondering why my books aren't available as standard audiobooks, it's because of the sheer investment of time and money it would take me. I'm always better off writing new words. If you ever see one of my audiobooks outside of Google Play, check the publisher name. I've had people plagiarize in the past.
But what if you're not on Google Play? Most devices have accessibility options that read text for you. I imagine it also won't be long until other players in the market allow this in their stores. It's a quickly emerging space.
