MARY has only ever seen white. The white of her walls, the bed, her clothes and the bio suits the Testers wear when they come in to take samples.
Every day is the same - white.
But for the new Tester, Vander, it is a reminder of his own life, trapped by indenture, forced to spend his life repaying the cost of raising him, like all the other Red Plague orphans.
When Vander decides to help MARY he starts a chain of events that will challenge friendships, revisit past betrayals and threaten the safety of a world teetering on the brink of catastrophe.
