Support rape crisis centers and enter to win an advance copy of The Snow Queen’s Shadow, by Jim C. Hines.
Fantasy author (and all-around cool person) Jim C. Hines (jimhines) is doing an online fundraiser for rape crisis centres, in recognition of April as Sexual Assault Awareness month. You can donate directly to your local rape crisis centre, or to RAINN (Rape, Abuse & Incest National Network, a US-based organization), and then send him an e-mail letting him know how much and to whom you donated. The initial prize is, as it says above, an advance copy of his latest book, but for every $500 raised he will add another prize. Further details via the above link.
