Rating: 4 stars
Cover synopsis: What would happen if you discovered that your family was one of the most powerful in human history, and that the source of the family's power was hidden around the world? What if you were given a choice -- take a million dollars and walk away or get the first clue? Amy and Dan Cahill take the Clue -- and begin a very dangerous race.
This is a fun new series. It reminds me a lot of the movie National Treasure: The characters have to comb the world -- and history -- to track down clues on a scavenger hunt that will, apparently, save the world. Lots of action, lots of education, lots of mystery.
I only give it 4 stars, though, because a lot of the characters are pretty unbelievable. And the plot was fairly predictable. But still, I enjoyed it, and can't wait to pick up the next clue -- er, I mean, book.
