The Crystal Clipper — B. Roman

In Adventure One of the trilogy, young David Nickerson deals with a series of family crises: his father's unemployment, his deafness after a serious illness and now, the mysterious disappearance of his sister Sally, crippled in the crash that killed their mother. Desperate to find her, David experiments with sacred crystals, and conjures up the supernaturally-powered clipper ship Moon Singer, which takes him on a fantastic journey to an uncharted mystical island filled with danger. The people David encounters all have a soul connection to him and their lives are destined to intertwine many times over. When he must rescue a young princess with the gift of healing in her song, held prisoner in a palace tower, David believes he will also rescue his sister Sally. Strangely, too, in this "other world," David finds he can hear for the first time in years. This gift foretells his destiny: to explore the contrast between goodness and evil, and to save a life that means more to him than his own.
