Invader from Mars: The Truth about BabiesHardcover, 9 May 2023

A hilarious new sibling story that ends with an out-of-this-world twist, for fans of Wolfie the Bunny.

One afternoon, Micah comes home to find trouble taped to the refrigerator door. His parents claim it's a picture of his soon-to-be baby sister, but Micah is sure it's a Martian.

When the baby arrives, his parents insist that she's perfectly precious--but Micah's no fool. He knows Martians do not come in peace . . .

But in a laugh-out-loud Show-and-Share day at school, Micah learns how special a baby sister can really be.
