Carter and Sadie Kane are two normal kids, just like any others. They are the children of an American dad and a British mother, separated in a custody battle after the death of their mother. Sadie lives with their deceased mother's parents, while Carter travels the world with his father, visiting various archeological sites. Ok, so they're not totally normal, but they used to think they were a lot closer to the average child until they found out the family secret.
When Carter and Mr. Kane come to London for a visit with Sadie, the three of them travel to a nearby Museum, presumably so Mr. Kane can look at some artifacts. But as Carter and Sadie watch their father working in the Egyptian room, they see him pull out two strange devices and begin to act strangely. The next thing they know, there is an explosion, and they are under attack. Before they can figure out what is going on, their uncle (who they thought was in New York) comes swooping out of nowhere to save them.
It is in the aftermath of these events that Carter and Sadie find out the weird truth about their family- a truth that makes their family situation seem entirely pedestrian by comparison. Carter, Sadie, and indeed the entire Kane family, are descended from an ancient line of Egyptian Magicians. And their father has just set events into motion which will make Ancient Egypt seem a lot more real. Can Carter and Sadie come to terms with their new identities in time to stop the building of a mysterious Red Pyramid? Only time will tell.
