Gods and Kings by: Lynn Austin

Gods and kings is about a prince named Hezikiah who lost his brother when his father sacrificed to one of his Gods. Hezikiah's mother and grandfather are christians, but keep it a secret. His grandfather tries to teach him the faith, but one day he leaves to go to the temple and says he will return……… Years into the future, his father promised his hand to one of his advisors daughters.  She is very exited to live in the palace, but when she gets there, she realizes he has other wives and probably not devote his life to her. The book is a cliffhanger, just a warning. But there are more books!
