After Nana passes away, Xavier, his mother and Comet the kitten all head up to Nana's attic to help clean it up. At first, Xavier is a little nervous. Though there are no dragons up there, it looks like a dragon's cave - it's gloomy, dusty and full of cobwebs. But as Xavier explores the attic, he discovers all kinds of interesting things: An old tricycle; Two monkeys made out of coconuts; A scrapbook full of photographs; A rocking horse with gold and red stars stuck to its neck. At the bottom of one box, Xavier finds a strange piece of fabric. It's thick, soft and green, and it makes his mother's eyes wet with memories. As Xavier learns more about this keepsake, he discovers more about his family and himself in this gorgeous picture book about intergenerational love and the power of memory.
