About this book
Alex is sure his brand-new brother, William, is an alien—he looks different, acts different, and nothing feels the same at home. So Alex starts collecting “proof” to convince everyone he’s right. With playful, cartoon-style art and a light touch, this picture book explores big-brother worries and the wild places imagination can go. It’s a funny, reassuring read for families welcoming a new baby and for kids who like silly mysteries with heart.
Setting: contemporary family home
