Call of Cthulhu for Beginning Readers
Very cleverly written (and illustrated) in the style of a Dr Seuss children's book. Love it. One little caveat - I was hoping to read it to my boy when he reaches 5yrs [sh], that is probably a bit young as of course some of the themes are a bit adult (basically there's a line about ppl being put to death ... I mightjust leave that bit out when I read it to the wee man).
