The name Roger Priddy may not mean much to you. Despite selling over 65 million books worldwide and having his titles translated into over 30 languages, he's not exactly a household name. What this author of Children's books might be however, is the Stephen King of the toddler set. At some point within my daughter's first year of life, someone her Auntie Jill bought her a copy of Priddy's MILLIE COW. This over-sized ''board book'' bore a TJ MAXX sticker for $6.99, with an original price of $14.95. While the value was undoubtedly a delight, what was contained within it's pages would prove to be something that was anything but.
