This was a great read, and I definitely recommend it to people who like a tad bit of mystery and a bit of action. Warren is a descendent of many Warrens, and as you can tell by the title, he is the 13th in his line. He is currently living with his Uncle in a hotel, and his uncle is about to marry a wife, Warren's aunt. She seems to be good at first, but after Warren's uncle leaves, she's not as she seems. Warren's family has a hidden treasure and Warren and his aunt are both on the look for it. But when things get a bit too harsh with Warren and his aunt, Warren sets out to find the treasure by himself. But what will happen to Warren? Read this nail-biting novel to find out! I would like to thank DOGObooks for supplying this book in exchange for this review.

National Geographic books are on my list of favorites. I always love the interesting, new, weird, and crazy fun facts that they have to share with everybody! I always love reading their almanacs, because there's so much in them, and you can turn to any page and read for hours on end. Also, I'd really appreciate receiving this book, because it's something that I could definitely use to pass time while in the hospital.
