King Arthur is expanding his kingdom's influence with Queen Guinevere at his side. Brangien is pining for her lost love, Isolde; Lancelot is fighting to prove her worth as Queen's knight; and Arthur is everything to everyone and thus never quite enough for Guinevere. The more she realizes how empty she is, the more she tries to claim herself as queen, the more Guinevere wonders if Mordred was right: she doesn't belong. When a rescue goes awry and results in the death of something precious, a devastated Guinevere returns to Camelot to find the greatest threat yet has arrived: the real Guinevere's younger sister. -- Adapted from book jacket.
