I have read the first four Cooper books, and I loved them all! I am an 11-year-old boy, and my favorite so far is Tombs of Anak, which is very thrilling and made me want to be one of the characters. I love their devotion to God, and I find their adventures very thrilling.
I loved these books - my favorite one is Flying Blind (now called Mayday ___________). A little too intense for age 10 but 12+ could handle it. Very interesting and keeps you on the edge of your seat until the very end!!!! :) Thumbs up!
Awesome books that every kid should totally read! Even though I'm 15 these are still some of my my favorites. They've got thrill and suspense and are a wonderful series for any young teen or even pre- teen. I think my favorite one (and this is hard to choose!) is probably the Deadly Curse of Toco- Rey.
