"Lengard is a secret government facility for extraordinary people," they told me.

I believed them. That was my mistake.  

There isn't anyone else in the world like me.

For two years, six months, fourteen days, eleven hours and sixteen minutes, Subject Six-Eight-Four - 'Jane Doe' - has been locked away and experimented on, without uttering a single word.  

As Jane's resolve begins to crack under the influence of her new - and unexpectedly kind - evaluator, she uncovers the truth about Lengard's mysterious 'program', discovering that her own secret is at the heart of a sinister plot...and one wrong move, one wrong word, could change the world.
