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.
I love the series when ever I read them I pretend I am Lila. I have read all but #6 I am reading that one now. I really enjoy these books because I love mystery and suspense. One of my cousins friends introduced them to me and I am glad she did.
