Blood on the Moon - Children of Egypt, #1

Mia Langdon-tomb raider and adventure-seeker-has everything she wants. Freedom. Independence. No chains (a.k.a. a man). Her troubles begin when she's attacked on a dig in Peru. Soon, she's forced to use her tomb raiding talents to find the flaming arrows of an Egyptian goddess. In the wrong hands, this weapon could destroy the human race-and nearly had. Used to doing things her own way, it isn't long before she figures out that she needs the help of Harrison Braden Stanton, her stuffy, but so yummy, Egyptologist and ex-lover.
There's one problem. He despises what she does. As Mia and Harrison find themselves in the middle of a battle between the Egyptian gods and goddess, there's no choice for the woman with a Grand Canyon-sized independence streak and the man working for the Egyptian god, Osiris, but to work together to prevent the destruction of all they love.
