Star Trek: Bitter Medicine [EPUB ebook] 

A routine salvage operation becomes a desperate rescue mission, as the U.S.S. da Vinci encounters a failing abandoned ship — that isn’t so abandoned! There is one survivor aboard the derelict vessel: a boy who carries a most deadly disease. Even as the S.C.E. works to salvage the ship, Dr. Lense must race the clock to find a cure for the boy — or condemn him to live out his days alone on the dying vessel!
