This is a time traveling romance. (But not icky romance! and not Harlequin Romance!)Basic premise: Chloe accidentally time travels back to ancient Egypt and has the body and memories of a Priestess.

He turns out to be the mage of Pharaoh Hatshepsut and a Lord to boot. The story continues with their lives in ancient Egypt and their encounters with Moses and his people and the exodus. This story ends with Chloe and Cheftu as they work to end their time in Egypt with plans to return to their respective eras. This is part one of four books. On a personal note, I think these books are very well written and have very interesting historical info. They tend to slide off towards the end, but well worth the reading.
