The Heart of the Kingdom — Sasha L. Miller

All Cenric wanted was a necklace to gift to his lady love, in the hopes it might persuade her to actually become his lady love. Instead of love, however, Cenric is informed of her engagement to someone else, wakes up to find his house burning down around him, and is dragged away by a man who might have saved him, but won't say much about why one necklace has Cenric running away from someone willing to kill to get it back.
