El circo (La casa de los ratones, 5)

School's out and Sam and Julia are getting ready for a great summer. One day, the circus comes to town! The director, the friendly Signor Roberti, hires Julia's mom as head chef, and mother and daughter have to go on tour. For the first time in their lives, Sam and Julia will be apart for a while, and they promise to write to each other about their vacations. But the two little mice miss each other terribly and in the end, they just want summer to be over so they can see each other again. Best friends prove they are best friends not only when they're together, but also when, after being apart for a while, they return and find that nothing has changed.
