The War Chamber - The Moon Singer, #2

David's trial by fire awaits. The unwitting hero and captain of the mystical sailing ship, Moon Singer, has yet to learn that his deafness is his greatest gift. This "disability", along with his possession of three sacred artifacts: The Singer Crystal, The Rose Crystal and The Wind Rose Compass, bestow David the power to save the lives of everyone he loves. Yet he feels that all the miracles he brought home on the Moon Singer have dissipated.
He's just as deaf as before, his sister's paralysis has returned, and his anguish over his mother's death is stronger than ever. At his mother's grave, David unleashes the power of his crystals and is transported to Coronadus, where he encounters a revered woman who wields the power of life and death, and helps David understand his mission. When a cataclysmic event occurs, David discovers that the past, present and future know no boundaries in the unending circle of life, and that he must follow his destiny, wherever it may lead.
