Tor has restarted their free e-book program with two free e-books this month and they promise to follow it with an additional e-book each month following. From an email I received and as reported by carandol in the
Deals, Freebies and Resources forum, there is a catch to the free e-books -- you must register for their SciFi & Fantasy blog.
The first e-books offered are
Dogland by Will Shetterly and
The War of the Oaks by Emma Bull.
