The Dragon and the Pearl - Jeannie Lin

Probably the best full length book in the series. Li Tao and Ling Suyin were a great couple and great individual characters (both got a raw deal character development wise in the first book). The plotline was filled with action and political intrigue. Best part, you don't have to read the first book to understand the characters or plot line in this book. One of the best examples of using flashbacks to tell the MCs back stories, like peeling back an onion. Such a great balance between the sexy times and the emotional intimacy times. Diplomacy and negotiations were dicey in Tang Dynasty China but the MCs didn't rise from poor kids in Luoyang to the Emperors' inner circles without gaining skills and reputation to use as capital during such dangerous times.
