Beldestine (en Inglés) - Paris Kaufman

Will has been captured, and King Brenton is far more powerful than Mageye City feared.

Rose, Myles, Mercy, and Sophie find themselves presented with a new mission-save Will. But when they find themselves trapped within a mysterious magical biome, they realize they need to save themselves first.

Hypnotic fireflies, magical vines, and a reverse desert stand between them and Alveraada. With continued controlled visions, newfound fears, and Myles's mental health on a serious decline, Rose doesn't know where to direct her attention. And when King Brenton's palace multiplies by two, everything becomes a riddle. One that begs them to ask a question.

What is the difference between a river and a waterfall... and why does the answer seem to be grief?
