Ooh, good one! I did carefully say "very few" because I knew of one piece of second-person writing (some of the scenes in Iain Banks's Complicity are written that way, presumably to enhance the feeling of complicity on the part of the reader), but that's a much better example.

Charlie Stross's Halting State and his still-being-written Rule 34 are in the second person, which some find mindbending but I quite enjoy.
