Is it Night Life (Pharoahs Rising, Book 1) by Elizabeth Guest --

A great pharaoh brought down by deceit and poison has awakened after 3,000 years. Now calling himself Adrian King, he is the rich, powerful owner of a pyramid-shaped casino in Las Vegas, where the artifacts are as real as the hieroglyphs on the walls. Christine Day has been born into a family of Egyptologists, but even at a young age, she intuitively knew more about the ancient people than did archaeologists. And at night, she dreamed of a strong, handsome pharaoh. When Christine attends a conference in Las Vegas, she visits Adrian's casino, hoping to see his legendary collection of artifacts. When they meet, they realize that they are soul mates. But someone else has come back from the Valley of the Kings, and this resurrected soul is pure evil. Exotic and erotic, this book will appeal to those who enjoy such films as The Mummy as well as readers who go for clever and suspenseful vampire books.
