"Sycamore seed siblings Merwin and Louise must use their wits and imaginations to navigate a mysterious and often dangerous world, filled with talking plants, monsters, meteors, and the fear of never finding the right conditions to set down roots and become big trees"--

"A little girl finds a sycamore tree named a “moon tree” and wonders why. When no one knows, her third grade class is determined to find the answer. Their quest leads them to NASA, an extraordinary boy who grew up to be an astronaut, a broken metal container, and a story more fascinating than they could have ever imagined." -- Amazon.
