About once a month Tor.com gives away a free ebook. This month's ebook is Walkaway by Cory Doctorow.
After watching the breakdown of modern society, Hubert, Etc. really has nowhere left to be—except amongst the dregs of disaffected youth who party all night and heap scorn on the sheep they see on the morning commute. After falling in with Natalie, an ultra-rich heiress trying to escape the clutches of her repressive father, the two decide to give up fully on formal society—and walk away.
Fascinating, moving, and darkly humorous, Walkaway is a multi-generation SF thriller about the wrenching changes of the next hundred years…and the very human people who will live their consequences.
You can download the ebook from Tor.com. It is available until midnight on the 19th.
