I had a book when I was in grade school and I think a small cousin of mine would adore it. It was about three kids that get caught up with these three? Two? Older women who take them traveling either through time or through dimensions.
Uh, I hate that I don't remember much more then that, but I both have ADD and I was 7 or 9 when I read it during my math class. I want t say it had something t do with either finding their father or that the women know him once upon a time. Also, the women weren't who they looked like being younger-looking but indefinitely older. It was a higher paced book then a 7 or 9 yr/o should be reading. Anyone? :/
