Camelot's Sword - Sarah Zettel - Paperback

The Paths of Camelot, book 3 of 4, completed series

King Arthur's love is his greatest strength and his greatest weakness.

Lynet's father holds Castle Cambryn in the name of Queen Guinevere. When Lynet's brother murders him, the castle and its people are thrown into disarray and Lynet sets off for Camelot to beg Guinevere to return and restore order. 

Meanwhile at Camelot, Lancelot's squire, Gareth has earned the wrath of his master and brought dishonour to them both with his womanizing and duelling. When Lynet arrives at court to make her appeal, Gareth sees a way to redeem himself.

But the danger is greater then either of them could have realized. For Lynet's fugitive brother has allied himself with Arthur's half-sister and sworn enemy, the sorceress Morgaine. Morgaine intends to use the troubles at Castle Cambryn to bring about Guinevere's downfall, and leave Arthur a broken man. Gareth and Lynet must put aside their growing feelings for one another and devote themselves to averting catastrophe.
