The year is 2425. Ever since an asteroid burst through our atmosphere, carrying with it a strange germ, nature has retaken the earth. Humanity's population, which peaked in 2044 at nine and a half billion, now numbers mere millions. No one died, other than normally. But almost no one was born, either.

Meanwhile, in the present day, Thomas Reeve and his cousin Kylie create a device which they hope will allow them to communicate with the future - a once-in-a-lifetime chance to discover what the world will be like more than four hundred years from now.

But their Time Tablet malfunctions, sucking Thomas and Kylie through a portal and into the year 2425 - and they have only 24 hours to return home, and save the future of humanity...

An innovative and visually sweeping picture book imagines Halley’s Comet observing Earth and its inhabitants at every pass, tracing human evolution over millennia.

First recorded traveling overhead in 240 BCE, Halley’s Comet returns every seventy-six years or so for a fresh glimpse of life on bountiful Earth. In a wondrous story told from the comet’s point of view, the creator of A Green Place to Be weaves scenes of Halley’s hurtling through space with views of Earth and its evolving flora and fauna below. Even as humans gaze up in search of the celestial wanderer—tracking the “broom star” in words and pictures—the comet gazes down, forming gentle conclusions. Each visit reveals how curious and creative humans transform the planet, contributing war and pollution but also a boundless capacity to love. What will the comet find when it passes again in 2061? Time stamps and thorough back matter ground a lyrical and luminously illustrated story in sound historical and scientific research. A kaleidoscope of biodiversity, locales, and peoples, Cosmic Wonder gracefully charts the highs and lows of human civilization through the eyes of a sympathetic watcher.
