She has been crossing the dark between worlds for four hundred years, and she chooses her own Ring Masters.
Her newest is Tom: twenty-four years old, quietly the luckiest man alive, and entirely unaware that his luck is paid for. Every impossible rescue he pulls off - every door that opens early, every shaft that does not fall - is balanced somewhere else, in the same breath, on a stranger he will never meet. He does not know this yet.
He is about to learn it the hard way.
Aboard the Big Top - a living circus ship that smells of cedar and rain and remembers what home is - Tom and his made-not-born family cross the galaxy from one robbed and weary colony to the next. A grief-quiet giant. A being of contained starlight wearing the shape of a young woman. A small, ferocious mathematician who reads the world as odds. A family of fire dragons. Together they do the one thing the structures grinding those worlds down cannot survive: they make people remember they were never alone.
But the children scattered across the galaxy were not lost by accident. Someone designed the pull that draws the Circus from world to world. Someone has been listening for four years. And when his message finally arrives, it will not be a threat.
It will be the truth - and the truth is the most dangerous thing Tom has ever been offered.
