This was my favorite book of all time when I was eight. Well, it shared the designation with "The Bible for Little Tots." I have the best memories of holding the book, looking at the simple line-drawings within the chapters, relishing the science fiction world and the plucky little Sprockets, an escapee from the destroy bin. I read it repeatedly--until it was lost somewhere in my family's numerous bookcases (later thinned out considerably by Hurricane Katrina). It is a delight knowing that somewhere in the world there are some copies around! Maybe I will read Sprockets one more time...
