This series started out with a bang, but now by this, the third book, I am losing interest. I was really confused by Sabotaged. The tracers were not explained well, and I could not keep straight what "real" time was as opposed to "mixed up" time. Every chapter ended with a cliff-hanger, but overall there was no suspense. I didn't understand why Andrea should or should not meet her grandfather. The book started abruptly and ended abruptly, with no real resolution.
