---A very good young adult novel---
This is the story of two girls, Erin and Irun. One lives now in New York City, and the other belongs in ancient Egypt 3,000 years ago.
For Erin, the 'now' she lives in is not all she'd like it to be. There are problems around her and within her that she cannot always understand. She is a loner until a young Egyptian boy, Seti, befriends her. And in her own time, Irun has much the same feelings of discontent, and another Seti tries to understand.
But there are other things that bind the girls--the same appearance, their relationships with their parents, and a cat called Ta-she. Perhaps the two girls are in some way the same person after all.
