Alec Greven wrote How to Talk to Girls when he was nine years old. This book is a result of his research. Initially, Alec self-published and was discovered by a publisher at a book fair. He has written two sequels, How to Talk to Moms, and How to Talk to Dads.
Nancy Yi Fan began writing Swordbird after 9/11 and a dream she had. She was inspired to write a story for a world at war, with a strong message of peace. Swordbill was published when she was twelve years old, with an initial print run of 50,000 copies. It made the New York Times Best-Seller list. She has written a prequel, Sword Quest.
These are both great books and we recommend them. Both are currently on the book shelves at B&N and can be found online as well.
