Jake O' Brien，one of the central characters in Sterling R．Walker's science fiction novel The Orphan Ship，has just received some bad news. The medical school he has been going to is closing down because of financial(财务的)problems；and to make matters worse，the only other medical program in the world also happens to be on another planet. Thus，in order to become a doctor，Jake packs his suitcase and jumps on board the passenger ship Atlanta to go to Mars!

When Jake and his cousin Lorina Murphy journey to Mars Station in search of educational opportunities，they never guess they will turn into life savers. But because of the extreme poverty and child exploitation(剥削)happening on Mars，these two cousins are forced to accept their true destiny(命运)．However，they are not alone in their efforts to save the poor “street kids”．Early in the story these two heroes are joined by the crew(船员)of the Ishmael，which in the course of the story，becomes a rescue ship and a safe place for over one hundred homeless children.
In this novel，there are different themes. While fighting the cruel people who sell the “street kids” of Mars Station，the colorful characters of The Orphan Ship also manage to fall in love，find wealth，and form lasting friendships.
The real power of the story comes from the characters' expression of fellow feeling—a feeling of understanding others because you have shared similar experiences. The characters in The Orphan Ship have a sense of social duty and spiritual commitment. For example，at one point in the story，shocked by the way the homeless children have been treated，Lorina notices “a pair of black children sitting under a streetlight begging food from passers­by”．Yet “no one gave the children a second look.” Fortunately，however，Lorina and her newfound friends—the crew of the Ishmael，which soon becomes the “Orphan Ship”—do indeed care for the children of Mars Station，as they join forces to provide them safe passage to earth and also a home. In this way the theme of compassion is the centerpiece of the entire novel.
