The Society's Traitor (The Discoveries of Arthur Grey, Book 1)

Eleven-year-old Arthur Grey has always wanted to be a hero, and a day has not ended right if he hasn't dug for treasure, plotted to stop thieving magicians, or written clues in his trusty notebook. But the real excitement begins when he's sucked through a transporting doorway and makes an amazing discovery: an entire society that investigates the truth behind all the legends and myths we've always thought were just stories. Now Arthur is launched into an adventure that takes him all the way to the mountains and jungles of Peru in search of a mysterious dragon-bird and the fabulous secret it guards. The problem is . . . someone else is after it, too. Arthur's chance to be a hero has finally come, but first he has to convince others of the truth before it's too late.
