Vertical Limits — Pam Withers

This time, when Jake and Peter stumble upon adrenaline-pumping adventure, it's high in the peaks of the Bugaboo Mountains just west of the Rockies.

Fifteen-year-old Jake is obsessed with solo-climbing a soaring granite spire. His best friend, Peter, is as absorbed with filming Jake for a video as he is in not divulging his secret fear of heights to the runaway girl who joins them. Though a talented climber, the surly runaway girl seems possessed by a death wish. When Jake arrives at the halfway mark and cheerfully hangs his overnight cot on anchors at a death-defying 150-storey height above the ground, all seems well, but the next day, a lightning storm begins to unravel this carefully planned high-risk adventure. When a crisis prompts the girl to put her life at stake for Jake, it falls to Peter to overcome his fear to get everyone home safely.

Packed with mountaineering lore and cliff-hanging tension, Vertical Limits features adventures in competitive gym climbing, outdoor urban climbing, and wilderness rock climbing.
