Richard Tucholka's Hardwired Hinterland: A Science Fantasy of Flight

Publisher's blurb:

Richard Tucholka’s classic world of fantasy flight returns, reorganized, revised and expanded to 250 incomparable pages of Tri Tac’s signature weirdness and humor set in the same universe as Fringeworthy.

The setting is an endless grid of 200 square mile island Environs, each with a unique culture and dangers and dumps of technological materials to mine, surrounded by impassable seas. Vintage aircraft are readily available as salvage, however, and sturdy adventurers make good use of them. Hopping from Environ to Environ trading, delivering the mail or searching for adventure, our heroes will face everything from cannibals to kaiju as they uncover lost treasures and brave the unknown.
