For every older sibling who has ever thought, "Hey, what about me?" and every parent who has ever used those magic words, "Just give me one minute."

Ruby loves nothing more than playing, especially with Mom. But Mom is always so busy with Oliver, Ruby’s baby brother — feeding him, changing him — and Ruby is tired of waiting. She has already looked at tons of books, but only Mom can do all the funny voices. Ruby has painted so many pictures and even dressed her dog, Rory, in a very fetching blue sweater. Babies are so boring! Maybe if Ruby puts her imagination to work, she can invent a way to make Oliver disappear to a place far, far away. Or would it be even more fun if she and Mom climbed aboard and went along for the ride?
