The Crystal Clipper [EPUB ebook] 

Deaf teen David Nickerson’s life is in crisis. His mother has died in a car crash and his sister Sally, now confined to a wheelchair, has mysteriously disappeared.

Desperate to find her, David experiments with sacred crystals and accidentally conjures the supernatural ship, Moon Singer, which transports him through time and space on a magical, fantastic journey.

The people David encounters all have a connection to him, their lives destined to intertwine. Strangely, 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 good and evil — and to save a life that means more to him than his own.
