A Challenge Met. A Calling Sought. A Faith Required. When Mara, Oathtaker to the ranking twin members of the Select, suffers an injury, her charges--Reigna and Eden--seek to determine their callings, while Dixon suffers over the potential loss of his beloved. As their allies disperse in response to a growing threat to their homeland, and as the forces of evil set out to destroy them, the twins journey across The Tearless, where in fulfillment of prophecy, they face three challenges. A single misstep may bring them to ruin; perseverance, to glory. To triumph, they must first believe.
