I hope his series is a success.  Still, how do you know it is a celebrity author book?  

All together now, boys and girls, "when they use the word LESSONS in the publicity. "

Ripken says,

“Connor is a character that I was able to help develop with Kevin based on my experiences as a kid who struggled with his emotions. I hope that the kids reading it find it to be fun and take away a few lessons from it.”

The first book will be titled Hothead.

Happiness: Giada de Laurentiis

Reading Meg Cabot's blog today, I learned that Food Network royalty and my favorite chef person, Giada de Laurentiis, is expecting her first child. You may recall Entling no. 1's heroic efforts to obtain a signed cookbook for her mother.

Hey, Emeril has several!
