Encala : Book 3 of the Heku Series. The Heku, #3

Encala, Book 3 in the Heku Series, finds Emily and Chevalier settled into the palace and life as one of the ruling heads of the Equites begins. The Equites elect Damon onto the Equites Council and he immediately finds himself at odds with Emily. Her independence and head-strong personality harshly conflict with his strict nature as one of the 'old ones'. As the Council City Cavalry struggles to keep tabs on Emily, the Encala begin their mission to gain her confidence and then jump to drastic measures to pull her into the Encala Faction.
The V. E. S. emerges, and come to believe that Emily and Allen are being controlled by the vampires. They quickly intertwine themselves closely with the city outside of Council City, the home of the Equites. Emily and Allen head to New Mexico to attend the wedding of Emily's cousin, and find themselves in the company of a strange heku. This heku befriends Emily, and comes to her defense when Chevalier finds out, and the Equites Council threatens to turn against her.
Emily's abilities strengthen, and her immense value as a weapon becomes evident to all three factions and the relationships become more tense and volatile.
