Together, the words and illustrations... tell a story that is sad and happy at the same time. It's a story that makes sense to everyone who ever had - or wanted - a grandfather.
-- The School Magazine (NSW)
This is an extraordinarily tender, beautiful story of friendship and loss. Stark combines searing poignancy with joyous humour and the most lyrical phrases to produce a quirky, endearing story that deeply touches the heart
-- The Sunday Tasmanian (AU)
This story touches the heart. It manages to be charming, warm, funny, poignant and sad all at once and it's told in such a way that a grandparent can reminisce and a young person can understand about friendship and loss not just through their own eyes but through the perspective of a much older person.
