Sam and their intrepid grandma bike around the world together in this sweet intergenerational adventure! Grandma Rose's job is having amazing adventures around the globe and writing about them. Her next trip is extra-special—because this time, Sam is tagging along! Together Sam and Grandma Rose will bike and explore national parks, villages, and sprawling cities, from bear sightings in Alberta to sloths in Costa Rica, and from gelato in Italy to bánh mi in Vietnam. Writing home in postcards, Sam details tidbits about each location's language, culture, and natural beauty. Sam soon finds out that Grandma is full of surprises—she’s up for any challenge, and wow, can she shred down those trails. Pedaling side-by-side, Grandma Rose will teach Sam to be brave and embrace new experiences both on a bike and in life. Whether trekking up majestic mountains or simply gazing up at the night sky, Sam discovers that the journey is not about the places you go—it’s the moments you share, big and small.
