My Friend Grandpa — Harriet Ziefert

Every summer Emma spends a month in the country with Grandpa. Emma enjoys her grandpa and the big tree that lives on his farm. She plays under it, swings from its branches, and climbs up high.
One day the tree is struck by lightning and is badly damaged. Emma is heartbroken. Will she ever be able to play in her tree again? Together, she and Grandpa find a way to save the best part of the tree.
Robert Wurzburg's evocative illustrations beautifully portray the compelling relationship that exists between Emma and her grandpa.
