A cool stone fortress, secret tunnels, and a mysterious new girl. Book 4 in the award-winning Wright Cousin Adventures series by Gregory O. Smith! “Jed’s lantern cast long shadows across the room. Tim gulped, not sure whether he wanted to stay there or not. It looked too much like a creepy dungeon!” The Wright Cousins are helping to restore a stone fort dating back to the American Revolutionary War. They expect hard work, but find more: secret passages, pirates, dangerous waterfalls, and clues to a hidden treasure of gold. There is also a new girl helping out who has a fondness for swordplay. Could she really be a princess in disguise? Join the Wright Cousins as they try to unravel their most puzzling mystery yet! "This is my new favorite series!" -- Anne R. " Outstanding Kid Series! I normally don't review books on here [Amazon] unless highly impressed! So many children's books today are such a poor excuse for literature - poor plots, undeveloped characters, even poor spelling and use of English. What a delight to find a highly qualified author, Greg Smith and to finally find a series that are uplifting, well written and adventurous!" (Amazon 5-star review by Buzzyflight, Nov. 10, 2020) " Kids favorite book-- I sent my niece and nephew several books for summer reading. This has been the favorite of both kids...Appropriate for all kids, just good fun...Highly recommend."-Consultx " My kids have read the whole series and asking for more!-- My kids are very much into action and adventure books. We have read the entire series together during family reading time. They have loved all of them and now cannot wait for the author to write more. These books are full of tasty little tidbits of true information including some historical references and accurate STEM information applied to situations in the book. I loved these for my kids."-Clint G " Mystery and Fun-- Purchased for my grandson--I found it to be quite a thrilling read--perfect for an almost 11 year old. Full of fun and adventure."-H. W. Longfellow " Great new series (to us)-- Bought for a 7 year old bookworm granddaughter who loves adventure stories and read it in almost one session!"-Reviewer in Canada " Worthwhile books-- Wonderfully written story, my son has devoured all 12 of the books in the series."-Susan " Couldn't put the book down!-- I purchased this book for my eight year old granddaughter. She enjoyed it so much she asked me to purchase the next book in the series, Desert Jeepers!"-KJD Good friendships always make life better.   Gregory O.
