Every year, Pat Rothfuss hosts Worldbuilders, which raises money for Heifer International via auctions and a lottery.

How does the lottery work? Pat says, “For each $10 donation you give through our Team Heifer page, your name gets entered into the lottery. Donate $50, you have 5 chances of winning. Donate $1,000 and your name is in the hat 100 times. We have had folks who donated $20 walk away with highly sought-after, signed, limited edition books.”

This year, the lottery includes a chance to win set of signed The Lightbringer Series books in trade paperback — or perhaps some other very cool signed SFF donations. (Check out some of the amazing loot you could win, HERE.)
