Disgraceful - The Death Dealer, #4

Chaos has descended on Glenbard. The people are starving, martial law has been imposed, and the country is marshalling for war. With the King of Thieves arrested a violent upstart has stepped into his place, leaving the people too terrified to take stand. From her cell in prison, Grace Hilren can only watch and scheme. Chosen by Glenbard's patron goddess, Grace is filled with a grim determination to save her city and its people.
But Grace's foe isn't a petty thief or highwayman, now she faces the crown itself. With sword in hand Grace will do whatever is needed to bring justice to the land.
