The Secret Queen

Praised solely on her looks for years, Lia was eager to put everything behind her and start anew... Until she got kidnapped and tossed into the harem of an unknown ruler. Desperate and afraid, Lia makes a deal with Karian, the handsome yet ruthless regent to the king, who seems strangely drawn to her. Will Lia be able to keep up appearances as Karian's concubine long enough to search for the hidden assassin in their midst? And once she does, will that be the very leverage she'll need to make her escape?
