Ascent is the 3rd in a series of books focusing on Peak Marcello, a teen whose life revolves around mountain climbing. His summit of Everest with his father in the 1st story was not on Peak’s terms. In book two, both extreme action and characters are brought into Peak’s life as he attempted to climb in Afghanistan. For his 3rd major climb, he just wants to return to the natural art of climbing, to have a “clean” climb. But in extreme sports, it is rare anything is easy. This reviewer read Ascent as a stand-alone 1st and it can hold its own as that, though knowing more of the background story with his father Josh, Zopa the wise spirit, and other characters really gives the story depth. Once the climb begins, Smith’s pace in events picks up, though the mystery and twists in the 1st half of the novel keep readers interested too. This is an additional purchase, especially if your library already holds Smiths earlier Peak stories.
