In celebration of the paperback release of his latest novel Castle, the excellent J. Robert Lennon is giving away iPad and PDF versions of his Video Game Hints, Tricks, And Cheats: Essays, Exercises, Riffs, Gags, And Other Incidental Writings, “a collection of random, mostly comic writing from the past dozen years, including pieces published in Harper’s, Granta, The Los Angeles Times, McSweeney’s, and elsewhere.”
