The Mystery of Welles Creek (Paperback) (ISBN-13: 9798235071230)

When Jim and Dave set out to build a secret hideaway in the woods near Welles Creek, they expect nothing more than a summer adventure.

But when they stumble upon an abandoned shack hiding a Cold War-era bunker beneath it, their discovery pulls them into a mystery far bigger than they imagined. Joined by Lily and Luca, the friends uncover hidden codes buried in vintage comic books, a sealed underground lab, and whispers of a long-forgotten experiment.

As clues begin to connect, one question grows impossible to ignore:

Was something hidden down there... or was something locked inside?

As the legend of the Beast of Welles Creek begins to make sense, the group must decide how far they're willing to go-and whether some mysteries are better left alone.
