for why his adopted little brother is just like him when a pesky kid on the playground questions their physical differences in this charming picture book.

When they hear the singsong tune of an ice cream truck, two brothers race to get in line! Big brother beats little brother and holds their spot. But when little brother catches up, another kid challenges him joining his brother in line: no cutting! Everyone knows that cutting doesn't count when you're siblings, but the kid doesn't believe they can be brothers when they don't look anything alike.

The brothers may not be biologically related, but they're still brothers, and they have so much else in common! They both like candy way too much, love swimming but hate baths, and know their parents love them. Big brother knows that differences on the surface don't matter when in his heart, his little brother is just like him.
