Silence and Stone (1) (The Faeries' Promise)

Unicorns are now free, but other magical folk are still in hiding—except for one faerie, Alida, who is a prisoner in Lord Dunraven’s castle. That is, until she escapes and a fierce struggle begins. Alida fights to free the faeries from the terrible promise they were forced to make to Lord Dunraven—but Lord Dunraven is desperate to continue denying his people the hope they derive from the existence of magical beings.
