I'm from the future. We need you.

Ever since he learned about climate change, twelve-year-old Jonah has dreaded a weather-beaten future where not even his asthma medication can save him. Luckily, a girl from that future arrives just in time to throw Jonah a lifeline.

Sunny won't say. But how can Jonah win over 600 classmates when the only thing he dreads more than the end of the world is talking to other kids?
