How will a life as slave, thief and assassin prepare Amerith for the Warden's role, protecting the King's daughters?

The girl Amerith, a slave plant gatherer for a Potions Master, is thrown out as too big to fetch all the plants the Master needs. Surviving trials and adversity, she grows up to be a skilled thief until she finds herself on the business end of the headsman's axe.
Two purses exchange hands; the "young dead girl" rises to become a world-class assassin until she accepts the position of Warden Mistress to the young Princesses of Lindebalgh.
Her mentor and her debt will return to wreak havoc on more than her life.

Amerith is a short side trip that adds to the experience of Toile and its
characters. It is best read between Book One, The Faux Princess, and
Book Two, The True Princess.
