This is a great book for a road trip. Lucas is the tiny twin brother of Lucy. Both are adopted to assist John and Tali, the protectors of life on Earth, using the powerful gift of the Fern. Children learn a love for Nature and the Earth in this Amazing series, while appreciating the need to lend a hand to protect all forms of life. Fun facts and Crossword puzzles to match the story are included. This is the first in a series leading to our National Park, Jr Ranger Adventures beginning with Paul Bunyan in Yosemite.
