Divine and Conquer [EPUB ebook] 

Since joining the Terran Intelligence Organization, Silver has been ignoring letters from his old Order to return. That is until they sent one that he could no longer avoid. Unable to refuse, Ketayl is the only one he trusts to help him.

Ketayl takes the opportunity while they are at the Order’s headquarters to go through the Central Seat’s library, hoping to find some kind of lead to help with their search for necromancers. She finds herself in a precarious position of having to hide her arcane abilities along with playing her part in helping Silver.
