Yak's Vault

When seventeen-year-old Jake's grandfather dies, he leaves behind an iron safe, a pocket notebook, and a human skull carved with strange numbers. Jake's mother wants the skull thrown away, but Jake senses something more. Then their shady neighbor, Chad Miller, shows up asking too many questions. That night, a thief breaks in. The skull is stolen—but so begins a chase into the unknown.With his fearless best friend Liam and loyal dog Tank, Jake deciphers a code hidden on the skull. It leads to a legendary treasure: the Yak's Vault, hidden for centuries in the remote Blackstone Mountains. But Chad and his gang are always one step behind, willing to kill for the gold.What follows is a breathless adventure across roaring rivers, through abandoned monasteries, and into lightless caves where an ancient, mad guardian waits. The boys face mountain lions, treacherous cliffs, a monster in the dark, and their own growing terror. But the real danger is Chad, who will stop at nothing—even murder—to claim the vault for himself.In the end, the treasure isn't what they expect. And the cost of greed may be higher than any of them imagined.
