Charmed Idol (Fated Touch Book 8) - Fated Touch, #8

For Jane, the cold winter of exile creeps up on her and her friends in their new abodes in Mechta. However, fate intervenes in the form of an offer of clemency from an old friend of Caius. The catch is they must earn their pardon by protecting the canta, a young woman of exceptional ability who must sing before the faithful of Gad at the Edict. They agree to the task and find themselves at one of the holiest cities of Gad, Sacratia.
Though under the sanctuary of the canta, their troubles with the Blue Binds haven't ended and they soon find themselves clashing heads with their old foes. On top of old troubles, new problems arise in their role as protectors to the canta. Their protection becomes essential as their mysterious foe tries to stop the canta from performing, even if it means sending her for a personal performance before Gad himself.
If they fail then it's the final curtain for all of them.
