When Marley and her little brother Gregory set off on what should be an ordinary family camping trip, she can't shake the feeling that something extraordinary is waiting for them in the forest. A glowing map, mysterious girls called the Watchers, and whispers from the Hollow lead Marley into a world where trees breathe, shadows hunt, and ancient secrets remember her name.

As she discovers her bond with the Hollow, Marley must face the First Flame, survive the Emberroot's test, and plant the Seed of Return before a creeping shadow consumes everything. Guided by courage, her mother's hidden past, and unexpected allies, Marley learns that she isn't just exploring the forest-she's part of its story.

Packed with adventure, wonder, and magic, this enchanting middle-grade fantasy is perfect for fans of Percy Jackson, Keeper of the Lost Cities, and Wings of Fire. Step into the Hollow, where sparks awaken, shadows whisper, and only the brave walk between worlds.
