Phaethon

Hackers, fae, and a new breed of corporate greed battle over the future of the human race.... Hacker couple Jack and Rosie crack technology, but the newest device, the Phaethon, isn't like other phones. The parts are junk, yet it can do the impossible. Through gentle prodding and data theft, they learn it's powered remotely...by a living creature. Cracking the Phaethon enters them into a war. Some, like Calthine, the bitter Bogle, are on their side. Others are controlled by a new type of fae; the bosses of the Phaethon corporation, who have steel for eyes and iron for souls. Now, the hackers have to fight creatures they've never heard of to save the friends they've just made.
