When nature is in danger, who will answer the call?

Millions of monarch butterflies have completed their extraordinary migration from the United States and Canada-only to face a new threat in their winter sanctuary high in Mexico's Sierra Madre Mountains.

Sydney can talk to animals, and the monarchs are afraid.

As chainsaws echo through the oyamel forest and mysterious drones circle overhead, the butterflies-along with a trio of horses and a determined little dog-warn Sydney that their fragile habitat is being destroyed. If the forest disappears, the monarchs' migration-and their survival-could be lost forever.

Saving them won't be easy.

Sydney's science-minded twin sister, Sierra, believes the solution begins back home in the United States, where conservation efforts can protect the monarchs along their entire migration route. As the sisters clash over strategy, responsibility, and what meaningful action really looks like, they must decide whether they can work together in time to protect a species that depends on two countries for survival.

Make Way for Monarchs is a middle-grade environmental adventure that blends suspense, heart, and real-world science. Part of the award-winning Eco Warriors series, this story weaves wildlife conservation and climate science into a fast-paced narrative that encourages curiosity, critical thinking, and empathy-making it a strong choice for classroom, library, and independent reading collections.
