Book excerpt: Interweaving lovely, meticulously drawn pictures with a story line that spans 5,000 years, Alexandra Siy invites young naturalists to explore the secrets of the world's oldest trees--secrets of the earth's climate, recorded in their tree rings, and secrets of the bristlecones' resilience, as a species that lives in the harshest of environments. Living for more than five thousand years, ancient bristlecone pines are the oldest trees on Earth. Recorded in their rings are "secrets"--scientific evidence of a changing planet. A volcano erupts in 2036 BC. In 775, a storm explodes on the sun. Lightning strikes in 1122. And during the 20th century, the temperature increases dramatically. What is the secret to the bristlecone's exceptionally long life? Alexandra Siy's lyrical text, paired with Marlo Garnsworthy's meticulously researched mixed media paintings, reveals the life cycle of the mysterious ancient bristlecone pine. "Still growing, safe and strong in its place in the sun, the bristlecone's secrets are waiting to be discovered by anyone who can read its rings."
