Free Sept 1 - Sept 7 on Tor.com:
Gardens of the Moon by Steven Erickson (Book 1 of the Malazan Book of the Fallen)
Available for Download in either Epub or Mobi
This is a free giveaway in exchange for signing up for Tor.com's ebook club, which entails providing an email address, no more.
This book was, to my mind, the weakest in the series, which really kicks off with book 2, Deadhouse Gates, but if you like Epic Fantasy that wears its role-playing game roots on its sleeve, I can't recommend this series highly enough.
