In the floating city of Atheria, humanity has survived the collapse of the old world by building a society rooted in sustainability and resourcefulness. But beneath its gleaming towers lies a truth long buried...
When Lani, an eleven-year-old girl with a love for her rooftop garden, stumbles upon a hidden underground library known as the Museum of Mistakes, she uncovers chilling records of the world before the Great Reckoning-mountains of plastic waste, polluted oceans, and desperate voices from a planet on the brink of destruction.
With the help of Juno, a brilliant scavenger of forgotten technology, Lani discovers more than history-she finds a hidden message from Maya, a girl from the year 2025, warning future generations of the mistakes that doomed her world.
Now, armed with forbidden knowledge and a responsibility far greater than their years, Lani and Juno must decide: will they risk everything to reveal the truth? Or will the secrets of yesterday ensure that tomorrow is lost forever?
