The Little Troll Who Smiled [EPUB ebook] 

Tobey is a young troll who loves to help people. He is an excellent example that being different is a strength. Even when people try to mistreat him, he never changes who he truly is, both inside and out. With his amazing heart and caring personality, he continues to help everyone with whom he crosses paths, wherever he lives. One day, a tough situation convinces him to move permanently to a new town. That new town appreciates him, and it is a blessing for both the townsfolk and Tobey.
