Liar’s Oath - The Legacy of Gird 02, Elizabeth Moon

Moon's The Deed of Paksennarion has been a blockbuster success in Baen's one-volume trade paper edition--and now the trilogy has a companion. The Legacy of Gird tells of Gird, the liberator, who teaches his people that they can fight--and win--against their Mage-born rulers, and Luap, Gird's sworn follower, who dares not lie and cannot tell the truth--nor face the future.
