*She is the greatest assassin her world has ever known. But where will her conscience, and her heart, lead her? * After a year of hard labor in the Salt Mines of Endovier, eighteen-year-old assassin Celaena Sardothien has won the king's contest to become the new royal assassin. Yet Celaena is far from loyal to the crown – a secret she hides from even her most intimate confidantes. Keeping up the deadly charade-while pretending to do the king's bidding-will test her in frightening new ways, especially when she's given a task that could jeopardize everything she's come to care for. And there are far more dangerous forces gathering on the horizon -- forces that threaten to destroy her entire world, and will surely force Celaena to make a choice. Where do the assassin's loyalties lie, and who is she willing to fight for?
