Clancy & Millie and the Very Fine House — Libby Gleeson

Clancy has just moved. He is missing his old house terribly -- the new house is much too big and much too lonely -- and he wonders how he will ever make it his home. With the help of his new friend Millie, Clancy builds towers to the sky and trains to the street outside, and together they build the home that Clancy thought he had lost forever.
