Query: Great Book Okay Ending

This is an awesome book by Pfeffer! It is a great book that I read when I was 10 years old and loved. It is probably meant for kids older than 10, but it is great! Micheal disappears and the family is torn apart. The mother takes it out on her daughters, and they turn against their mom. It is a wonderfully written book but the ending leaves you hanging. You never know what happens to Micheal, and you feel so upset. Why don't we find out what happened? The book leaves you with a powerful feeling for days. I would prefer closure. But the meaning is so much stronger and sticks with you after the end. I wish there was a sequal, but in real life you don't always find out what happened to missing people, so it is very realistic.
