Ava Lin: Super-Duper Happy

From the publisher:

Ava Lin is in first grade, and she’s really good at dancing, making up games and finding treasure. This week she’s super-duper excited, because it’s going to be the BEST WEEK EVER. First, her popo—Chinese for grandmother—is coming to visit, and Ava can’t wait to show off the special acorn, button, Post-it note, hair clip and inside part of a marker that she found on the school playground. And second, this Sunday is the school walkathon. If Ava and her best friend, Kushi, manage to walk 25 laps, they will each earn a gold medal! But the week doesn’t go exactly to plan—like when Popo mistakes Ava’s treasures for trash, or when Ava discovers that fundraising for a walkathon is not quite as easy as she had hoped. Is there a way to make this week a super-duper happy one regardless?
