I'm excited to announce that a book I worked on earlier this year has just come out! Camp Secret, by Kathryn Dennis and Melissa Mahle (who, by the way, no big deal, is a former CIA intelligence agent), is a middle grade novel that follows four kids as they discover that their summer camp is really a training ground for junior spies. It's a really fun read, and you can read the first chapter here, or learn more about the book and the authors at their website.
