The Girl in the Box, Book 56

(Paperbacks available on Amazon in US/UK/EU)

Sienna Nealon is up against her most dangerous threat yet, and her enemies have stolen people dear to her.

They'll pay for that.

But she'll pay, too, because to free the ones she loves, she'll have to expose others to danger. It's too big a job for one person, even the world's most powerful woman. But will she manage to save them in time?

And will the sacrifices she make be worth the cost?
