Xavier McSweeney has a secret fear of heights. His dad says so long as he steers clear of high places, especially unfamiliar ones, he'll be fine. Normally, that wouldn't be a problem. But X is signed up to test out a two story model of a rock climbing wall in less than a week! If he doesn't go, he's sure his friends will think he's scared. So he doesn't say anything about his fear-until it's almost too late.
