I wrote I SPY I LOVE YOU for Valentine's Day. The I SPY readers help children learn to read. My grown sons Dan and Dave are the "ghost writers" for all of the I SPY readers. It's hard work because I ask them to call for objects that haven't been called for in other I SPY books. That takes a lot of searching through a lot of I SPY books, more searching than I could ever do! If Dan and Dave do call for something that was called for in another book, they try to call for it in a different way. This keeps the I SPY books fresh and challenging.
