Shine! Choices to Make God Smile by Genny Monchamp is an adorable children's book with a great message. It goes through many situations that a child might face... the temptation to sneak a cookie, for example... and then explains what the right choice is and how happy this makes God.
The overall tone of the book is happy and positive, exactly the type of book I like for my kids to read. The illustrations are colorful and fun. It's a great book to read to little ones and it could easily open the door for further discussions about making good choices.
