You can choose your friends, but you cannot choose your family ... or can you?
Now sixteen, the twins Lizzie and Maggie are educated young ladies who have not been called "the Mopsies" in years—except by their guardian, Lady Claire Trevelyan. With the happy prospect of choosing their own future, the girls can leave their dodgy past behind, and Lizzie can bury her deepest childhood memories where they can do no harm. Upon her graduation from school, Lizzie is awarded an enormous honor, but can she pay the price? Is she ready to be separated from Maggie and become the woman she believes she was meant to be—or will old habits tempt her into defiance and plunge her into disaster?
On a dare, Lizzie picks the wrong man's pocket and nearly loses her life. But these frightening events bear unexpected fruit: the dream Lizzie holds closest to her heart comes true in a most unexpected way. But this dream, too, comes with a price. Lizzie must decide whether her true family is the one she was born into or the one she chose that long-ago day when the Lady of Devices steamed into their lives.
