A must-purchase.'-STARRED review, School Library Journal. A bug-tastic and social justice-filled new early chapter book series! Bee and her friends love parties, but the upcoming Mother's Day celebration in her third grade class makes her feel all squirmy inside: are she and her dads even allowed to go? Bee and her best friends Sarah and Tiam-the Winged Wonder gang-love parties almost as much as they love bugs. So when their Grade 3 teacher announces that the class must come up with a winning party idea, the friends are so excited. But when Bee realizes that it's to celebrate the upcoming Mother's Day weekend, she is confused and worried: Bee has two dads. Is she allowed to celebrate, and are her dads allowed to come? But Bee quickly learns that she might not be the only one who's feeling left out. With the help of her friends and her parents, Bee must figure out how she and others in her class with non-traditional families can not only take part in the class party, but feel celebrated too.
