Janet Martin and Faith Kingston are two young American medical interns who are closer than sisters. When Faith's mother died, Janet's family took her in, and they've been inseparable since. Now, in the midst of World War II, they embark from San Francisco Harbor on their greatest adventure yet.

They travel to China during the Japanese occupation. They face incredible challenges, like bombings, lack of proper supplies, general chaos, and the constant threat of danger. Still, these brave women will not give up on their patients.

During a time in history when many women did not work, Janet and Faith buck cultural norms in Asia. They cling to their intense friendship even as the world seems to fall apart around them. War is hell, but these young women bring peace as they heal both bodies and souls.
