Dr. Simon Tam

A brilliant surgeon from a wealthy family who gave everything up to free his sister River from a secret Alliance facility. On Serenity he is both ship’s doctor and fugitive – and struggles with rough life on the edge of the system.

Simon Tam was one of the most promising young doctors on the core worlds. When the letters from his younger sister River at an elite academy turned strange, he was the only one who noticed something was wrong. He gave up his fortune and his career to free her from a secret Alliance facility.

On Serenity he is both ship’s doctor and fugitive. He is polite, stiff and feels out of place in the rough life on the edge of the system. He would do anything for River, and that puts him in danger again and again – all the way to the stake in “Safe”.
