The most horrific children's book ever

I just did a quick search to see if we have Don't make me go back, Mommy : a child's book about ritual abuse. We don't. The scanned pages are horrific (particularly in the "part 2" post). I wonder how many people have actually read that book to their children? Are there really parents who worry that someone may be trying to perform satanic rituals on their children and who therefore feel that their children must know what kinds of behaviors to report?

Where's my cow?

I cataloged Terry Pratchett's Where's My Cow? (and was the first person to add a 2nd cutter number to the call number in the master record) - I'm not sure what children would think of it, but, as a fan of Pratchett's Discworld, I thought it was hilarious. I had some trouble thinking of Sam Vimes sitting down and reading a silly picture book, but, once I got past that, his "Where's my daddy?" was perfect. Young Sam is a very odd-looking child, though.

It's not actually possible to get everything in this book unless you're familiar with the Discworld, but young children might still have fun with some of the things they'd get to do when certain characters come up (not sure that their parents will necessarily appreciate the spitting).
