This is no time for a learning experience… Sage Curtis, engineering student and reluctant Savior of the Earth, is not having her best month ever. She is almost reconciled to the idea that she will have to use her Thunderbird powers to reverse the damage humans have done to Earth’s climate – but those powers haven’t helped her much so far. While recovering the world’s supply of fresh water from the Slavic underworld, she and her friends unwittingly triggered a ten-foot snowfall across the Northern Hemisphere. Now people and crops are dying, and the snowmelt threatens to cause the seas to rise, wreaking further havoc. Sage and her friends have to get rid of the snow safely before they can roll back climate change. The clock is ticking, the learning curve is steep, and the gods will be no help. They have already said that if humans can’t fix the climate, They will destroy the planet and start over. Sage must use everything she knows about both science and magic to save the Earth – and even that might not be enough.
