Anne Ursu's The Disapparation of James was on my list of circus novels. A family takes their children to see a circus (more Big Apple than Ringling Brothers). The second-to-last act features a clown magician. He asks for a volunteer from the audience. Young James Woodrow is chosen, and the clown puts him in a chair. The clown lifts the chair over his head, and James disappears. And can't be found. The police are brought in, the clown is tracked down, no one can find James. A cop is placed in the Woodrow's home. James' sister, Greta, decides to make drawings of her brother's adventures: "he's in the jungle with lions and tigers and bears and dogs. He's under the sea with mermaids and funny fishes and otters and underwater dogs. He's in the sky with magic birds and flying dogs. He's on other planets with flying dogs and talking bears...." Then she decides to make drawings of the things he loves: "the stuff he likes and doesn't like and stuff. He likes peanut butter sandwiches a lot. He hates tomatoes because he thinks the seeds look like eyes. He likes otters because they are so cute and of course he likes puppies because everyone likes puppies." Is that 7 year old girl or what?
