The tiny mansion

Twelve-year-old Dagmar and her family spend a summer living off-the-grid in a tiny home parked in the Northern California redwood forest, next door to an eccentric tech billionaire and his very unusual family.
"The last thing twelve-year-old Dagmar wants is to spend her summer vacation squished into a tiny house with her dad, her stepmom, and her annoying five-year-old half brother. But after a sudden financial setback, her family is evicted from their Oakland apartment, and that's just where they end up, parked among the towering redwoods of Northern California. As Dagmar explores the forest around their new and (hopefully) temporary home, she discovers they are living next door to an eccentric tech billionaire and his very unusual extended family. There's his brother, a woodsman who sets dangerous booby traps all over the place, and his sister, a New Age animal lover who meditates to whale songs in an isolation tank. And then there's the billionaire's son, Blake, who has everything he could ever wish for -- except maybe a friend. But when a wildfire engulfs the forest, everyone -- rich and poor, kid and adult -- will have to work together to escape. And with both families at risk of losing everything, it turns out it's not the size of the home but the people you share it with that matters."--inside jacket.
