In Book 6 of the 39 Clues series, Jude Watson's In Too Deep, Amy and Dan head to Australia, where their parents visited a friend shortly before their death in the house fire. While there, they have dealings with Irina Spasky and Isabel Kaba, but are not quite sure which woman they can trust. Amy and Dan learn much more about her parents' death, gather a few new clues, and, of course are involved in a lot of dangerous exploits.
This was a fine addition to the series, and I liked Amy's emotions about her discoveries. I have trouble following all the clues, so I would not do well at the online game! I do wish that Scholastic had put these in better bindings. Like the Lemony Snicket books, these start shredding the first time a student touches them, and this collaborative effort between so many fine authors deserves better.
