One of my favorite books growing up was a Weekly Reader book called "Andrew Henry's Meadow" written and illustrated by Doris Burns. It's about a kid who loves to "invent" things but his inventions make his family crazy, so one day he runs away and finds a meadow where he builds himself a house (fort) and where he can work on his inventions. He is soon joined by other children whose families also do not understand their hobbies and Andrew welcomes them to his meadow and helps build each of them their own house where they can enjoy their hobbies. And, yes, there is a happy ending to the story!
This makes a great gift for young readers. All kids go through the "not fitting in" stage and will relate to Andrew Henry. Amazon had this for awhile when the 40th anniversary edition was released. You can also purchase directly from the publisher: San Juan Publishing.
