When a science project goes awry, two student activists travel through time to learn how to protect our Earth from plastic pollution in modern times.

Studious environmentalist Charlie is stuck with a science fair partner who seems like her complete opposite: Charlie wants to save the planet, and all Oliver wants is to doodle in his notebook. But when a mechanical mishap sends the two traveling back through time, they’ll have to work as a team to return to the present day.

In order for the time machine to send them back, the unlikely duo must gather data on recycling throughout the ages – from sustainable marketplaces in Edo Japan to garbage-gobbling pigs in 19th-century NYC. Yet the closer the team gets to the present day, the more that plastic presents a problem: they’re running out of time.

Harnessing their frustration over the daunting ecological future they’ve inherited, Charlie and Oliver discover the ways in which they can use their sustainability knowledge to return home and build a better earth.

In this sweeping educational adventure that transports readers across continents and centuries, Washington Post contributor Katie Wheeler invites readers into the history of recycling and how students can reduce plastic waste. Wheeler’s fresh journal-style graphic novel acknowledges the reality of plastic pollution while offering accessible activist solutions, playfully-illustrated sustainability tips, and an optimistic look into how modern scientists are combating waste.
