...will grab you by the throat and not let you go until you reach the very last word. Man, oh, man! I didn't think these 39 Clues book could get any better, but this one gets this suspense, action, creepiness, and mystery up to a whole new level. Dan and Amy Cahill get a strange telegram while in Cairo, Egypt that says they should go to a certain locker in the Cairo airport. What they find sends them deep into Russia with only 36 hours to traverse that enormous country to find the greatest Clue yet. Of course, they can't do it alone, so they have to make an alliance with one of the most unlikely branches of their deadly family. AND they have to solve a lot of mysteries and dodge ruthless killers along the way, climbing inside gigiantic statues and hiding in coffins with bones of long-dead rulers! I tell you, I couldn't stop reading until I got to the last page! For fun, exitement, and heart-stopping danger, you can't do better than The Black Circle!
