Comments for Shatterproof
Shatterproof by Roland Smith is the fourth in the Cahills vs. Vespers series. It's the last one though that reads like a 39 Clues book. The last two, Trust No One and Day of Doom bear little resemblance to the rest of the series.
Dan and Amy are still under the thumb of the Vespers. Now they are ordered to grab the largest diamond. Meanwhile the captured Cahills start trying to fight back — with some good and some awful results.
On the home front, it becomes apparent there is a mole in the Cahills operation. Now here is where I briefly got hopeful. It would have been fun — especially with the title of the fifth book, if Amy's home town boyfriend, Even, were Vesper One.
Instead, though, the possibility of a love triangle is explored. I realize Amy Cahill is older now and the age of the typical love triangle heroine, but she doesn't have the time for such nonsense. She's also too smart for it.
