Socks, I wish I could remember, but it has been almost a year since I read the book. Sorry....

Spoiler ahead.

When they parted, she left the key to gate in his hand, and even though he didn't know about the stone in the little house (or did he?) he knew there was a reason why she took him to that spot and he saw her set the house in the water. Smart as he was, he was able to crack the code to open the box and I think he took out the stone, left it in the water (at low tide) and then put the key back in the box, hoping he would meet her again and be able to return it to her. It is never said how he knew there was something of value in the house though. At the end where Max has the ability to open the box seems to bring it full circle.

I thought it was a beautifully written book, and a great ending, even though it does make us wonder. Isn't that what book are supposed to do?

Thanks, Maxmom, for taking time to answer. I enjoyed the book but felt the end didn't wrap up clearly. I do appreciate your input, though. The book certainly is popular.
