Ssshhh…it’s a secret! Kids will have hours of fun playing the games and activities in this refreshed and updated version of our bestselling secret book. My Book of Secret Stuff includes an amazing bonus dual-ended pen; one with a regular pen, and the other with invisible ink that is revealed with the black-light torch within the pen! There is also room to write personal journal or diary entries. Write in the book with regular pen, or use the special black-light pen and the writing will not be revealed without the black light, keeping those private thoughts extra secret!
