Book excerpt: Teaching your little brother his first word—dibs—is funny. Until he starts calling dibs on everything, from your parents' bed to a real airplane to the White House. What's next? Calling dibs on the moon? Sure enough, Julian's little brother, Clancy, calls dibs on NASA and blasts off into space! Julian is glad to have Earth all to himself...at first. But Julian begins to miss Clancy. Can he harness the power of dibs to rescue his little brother? This humorous take on sibling rivalry is by Laura Gehl, author of the hilarious picture book I Got a Chicken for My Birthday.
