Scifi authors pose half-naked on this genderflipped book cover—for charity

For a splash of levity on this frigid (here in Philadlephia, anyway) Friday, we bring you this amazing piece from io9 about a group of sci-fi and fantasy authors who got together to do a gender-flipped parody of Poul Anderson's Young Flandry. Featuring Mary Robinette Kowal, Charles Stross, Pat Rothfuss, John Scalzi and Jim C. Hines, the shoot is part of an effort to support the Aicardi Syndrome Foundation.

We'd love to see someone remake Vonnegut's Sirens of Titan. What book cover would you like to see given the same treatment?
