This exceeded my expectations. Set in a post apocalyptic works where most people have very little in the way of material comfort and they spend all of their time in a virtual reality world. The creator of the world dies and reveals that he will leave his vast fortune and the VR world to whoever can solve a series of puzzles which he created and hid. There are so many great references to the 1980s and a madcap race to the finish with very evil corporate types competing against a group of scrappy protagonists. It's really good!
