Ariel is a natural for adaptation to audiobook -- a nonstop, tightly plotted adventure novel with lots of exciting, well-told combat sequences that De Ocampo just nails. And, of course, the book is available as a DRM-free download (Boyett's something of a copyfighter, which makes it great all around.
Incidentally, Boyett's holding a competition in which he's asking for readers to send in photos of their "ganked out" original copies of Ariel (mine's much-loved and has been read literally dozens of times), with the owners of the most beat-up copies winning signed new editions. Sweet deal!
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
