“A thrilling adventure full of magic and wonder. John August is a master storyteller.” —Ransom Riggs, #1 New York Times–bestselling author of Miss Peregrine's Home for Peculiar Children

From acclaimed screenwriter John August, Arlo Finch in the Lake of the Moon continues the spellbinding fantasy adventure series about the magic that lies just beyond our world.

Some legends are real.

For Arlo Finch and the Rangers of Pine Mountain Company, summer camp is more than canoeing and hiking. It’s also a chance to search for ancient forest spirits and discover mysterious messages encoded in tree bark. But when Arlo and his best friends Indra and Wu stumble upon clues about the long-lost Yellow Patrol, Arlo uncovers a stunning history that leads right back to his very own family.
