From their sheets and pillows to their books, fruit, and furniture, nearly everything in Jamie’sand Megan’s lives has come from nature. Learning to truly understand what surrounds them, they discover that the air they breathe includes water and life-giving gases and that the seeds they find will grow into vegetables. Color illustrations make this simple, stirring story come to life, and the activities and glossaries included for further enrichment help to educate as the story entertains.
