Best-selling picture book creator Mo Willems continues his charming Elephant and Piggie first reader series. The books feature two lovable and funny characters: an optimistic (and sometimes reckless) pig and a cautious, pessimistic elephant. Children who sat on their parents' laps to have Pigeon read to them will eagerly take the plunge with these books to start reading on their own. Each book has been vetted by an early learning specialist. These sweet and surprising stories are a much-needed breath of fresh air in the early reader arena.

In I Am Invited to a Party! Piggie is invited to her first party. She doesn't know what to wear, though, so she asks her best friend Elephant for help. Elephant's advice is odd to say the least, so Piggie will try on all sorts of zany outfits before finally arriving at the party for a hilarious surprise.
