“Agatha, look,” Tedros said.

She followed his eyes to a titanic wreckage of vines, trees, and glass thirty yards off the path, glittering in sun mist like an imploded greenhouse. Tedros deviated off the trail to get a closer look, Agatha tailing behind him. As she neared the colossal ruins, at least fifteen feet high, she glimpsed petals and leaves flaking off the tree trunks, catching the light like new blossoms in spring. But drawing closer, Agatha saw all these petals and leaves were dead, sprinkling the dirt between decaying blue frogs. Agatha ran her hands along one of the fallen trunks, her fingers tracing letters etched into the wood: HIBISCUS LINE.

“It’s a Flowerground train,” said Tedros, inspecting a dead vine. “Whole Forest seems to be dying. Maybe the sun’s too weak to keep any of the plants alive?”

Agatha didn’t answer, still riled up from their earlier spat.

“But why would the sun be any weaker than before?” Tedros prodded.

Silence hung awkwardly.

They both mumbled about getting on and spun from each other, as if to follow Princess Uma, but she was far ahead on the path, a miniature shadow, and they had to run after her when they realized she wasn’t going to stop.

They followed her through Willow Walk, Thicket Tumble, and Pumpkin Point, as rickety wooden signs named these parts, which all mirrored portions of the Blue Forest back at school, only bigger and drearier. Occasionally Uma stopped to let them eat a few sludgy meerworms from her pockets (Uma herself abstained, saying it’d be rude to eat her “friends”) or to ask a sparrow or chipmunk to guide them to the nearest pond, where they’d inhale palmfuls of brackish water. Still, for all the menace of the Woods, they didn’t come across anything that resembled a human being, let alone a zombie villain, and Agatha started to wonder if she’d imagined everything that had happened on Necro Ridge.

As if reflecting her easing mind, the tangled forest opened up the farther they went, with more air between trees and the thorny brush turning into a green carpet of grass, though Agatha could see slivers of yellow starting to creep in. When they passed a gilded plaque that said FOXWOOD, Uma’s shoulders noticeably relaxed, and soon the dirt path widened so that they could all walk together, breathing in clearer air and a tangibly safe feeling, as if they’d entered a protected realm.

“The oldest Ever kingdom,” Uma said, finally at ease.

Over the trees to the west, Agatha could see the thin spires of a golden castle shimmering like organ pipes, but her teacher was already steering them to the east, down denser paths.

“We’ll avoid the thoroughfares and go through the glens. Best to avoid you meeting any Evers for the time being.”

“Why’s that?” Agatha asked, but Uma was too busy gibbering to a passing bee.

By the late afternoon, they came upon a large stone well, its wooden roof draped in browning white roses, while a dove pecked at the dry bucket. Agatha brushed away the roses to read white words painted on the roof:
