The Sum of All Men

In David Farland's acclaimed Runelords series, a unique world thrives on the magical exchange of "endowments," granting superhuman abilities to those known as the Runelords. Young Prince Gaborn of Mystarria, disguised and on a quest to win the hand of Princess Iome, encounters danger when he uncovers an assassination plot against her father. As Gaborn and his bodyguard race to alert the king, they realize that the crisis threatens not only the royal family but also the very fate of the Earth itself.
