The Tower of Boran

"In the night sky over Caillte Saíocht, not a single star shines, and those who live below it must fear the corrupting touch of night-fever. The crystal gleam cast from the Tower of Boran is all that stands between the realm and utter darkness, but its power has long been fading. 

On her sixteenth birthday, Seraetia prepares to be named a priestess of the Sanctum, destined to restore the tower's light. As the events of this long-awaited day unfold, however, she learns that not everything is as it appears. With the life she thought she knew rapidly unravelling around her, Seraetia must ally with those who know the truth behind the land's peril, and fight to save her home from something darker than the night."
