"It's one thing to feel like an alien on your first day of school. It's another thing to be one.... the amusing text works seamlessly with the artwork... A fine read-aloud choice, this picture book explores what it feels like to be the new kid, whatever planet you call home." —Booklist

"Dewey Dew is blue, has one eye and an antennalike appendage on his head, and is from Planet Eight Hundred Seventy-Two Point Nine. But for his first day of school, he is heading, reluctantly, for Earth and Mrs. Brightsun's School for Little Learners. But nothing there looks, feels, or sounds quite right to Dewey Dew... Mack's pencil, watercolor, and digital illustrations are a delight. Though they've likely never met an ET, readers won't have any trouble decoding what the unfamiliar words mean or how Dewey Dew feels about his single eye, 3-fingered hands, and lack of hair amid the other students, who are nicely multiracial.  ET or not, the first day of school will be ootay." —Kirkus Reviews

"Little one-eyed alien Dewey is anxious about starting school on Earth... The alien perspective is at once relatable to kids and distant enough to provide a neutral, safe place to ponder the worries of starting school.... This is just the ticket for freshening up a back-to-school storytime or a first-day-of-school readaloud session."—The Bulletin of the Center for Children's Books
