Mouse has never had a friend quite like Pig. Pig is so incredibly kind, fabulously fun, but he also has a big secret--he's a tremendous worrier! When Pig gets the brilliant idea to throw a party for Mouse and their friends, he can't help but think of everything that could possibly go wrong. After all, what if a lion eats all the invitations? What if nobody comes? Or worse, what if everyone comes and has an awful time? In this adorable story, Linzie Hunter's charming, bright illustrations pair perfectly with her sweet and funny story about friendship and the endless wonder of what if that readers of all ages can relate to. This picture book is a great conversation starter in the home or classroom.
