nds of her imagination--and her older brother Mason's patience--as she lays out her plan for a new pet. A must-have for fans of Charlie and Lola and Olivia or anyone crafting a case for why they need a new animal addition to the family.

At the Museum of Natural History, first-grader Missy has a genius gigantic idea: she wants a wooly mammoth as her new pet. She'll name him Malcolm. They'll take bubble baths with strawberry-banana shampoo, and go on picnics, and she'll swing from his tusks. They'll be best friends.

Older brother, Mason, spots one mammoth-sized problem with her plans. . . .

But once Missy gets an idea in her head, nothing (not even the fact that mammoths have been extinct for ten thousand years) is going to stop her from getting her fuzzy new friend.

Missy and Mason are a winning new pair for the canon of sibling stories--when Missy dreams a little too big, Mason is always there to help pull her back, and when practical Mason plays it too safe, Missy helps push him to think bigger--and Missy Wants a Mammoth is sure to charm in a massive way.
