I've had several people asking about books for 6th graders who aren't interested in reading about death, mayhem, rape, abortion, cutting, and all those subjects that seems so prevalent in teen realistic fiction these days.
I've put together a booklist called "Books that Won't Make You Blush" (although maybe it should be called Books that Won't Make Your Parents Blush"?) and you will find it here. (There's also a link to it under the list of links on the right hand side of the blog, under the heading "Need Something to Read?")
There are some great books on this list, so dig in and enjoy! (And if you have read something that you think should be added to the link just drop me a line at firstname.lastname@example.org)
