I read a book I really enjoyed and passed it on and now it is missing and since I can not remember the title or the aurthor I am at a loss.  Its about these people who have/find a sphere/large round thing and build a boat to bring it across the ocean.  They end up on an island and think they have the answer as to what it is.  If that sound like somthing you may have read plese let me know!  Thanks for your help!
