*spoiler warning!*

I can never tell if the plot is actually predictible, or if I'm just way too familiar with Nancy Drew after all this time.

This was a fairly good book. It kept my interest all the way through, and a few surprises toward the end (like the real Catarina, and it was all revealed!) definitely made it a worthwhile read.

However. The side-mystery with the strange animal sightings... It was sooo obvious and easy to figure out, especially because of what was known about Mark, yet Nancy was completely stumped throughout the book. ( )
