The Ancient Spirits of Sedgwick House — Catherine Coulter

When Grayson Sherbrooke takes his son Pip (nearly five), Miranda (his love interest), her daughter, P.C. (a precocious eight-year-old), and Barnaby (an orphan who calls himself a barn cat) to Lake Windemere to the home of Lord Lyle for a month of fun and relaxation, little does he know what awaits him.

Lord Lyle, a big collector of ancient Egyptian artifacts, proudly shows off his collection to Grayson before he and his wife Lucy (nearly deaf but with an inner eye) leave to return to Egypt. There's an unknown child's sarcophagus with a bizarre curse, all sorts of Egyptian statuary, and a strange golden cuff. When Grayson picks up the cuff, he is thrown into a vision in a long ago past. Bad things are happening that could threaten him and his family. He realizes he must find out who the child is in the sarcophagus. And why opening the sarcophagus would bring death.
