Query: The worst book of the series

This volume shows extreme unbalance with the first half totally concentrates on the escape from Greece/the deliverance of Petra from the missles. The second half is very boring with many episodes copied straight out of the Bible, e.g. the openning of the earth to swallow the rebels. This is the only book in the series that I had to force myself many times to finish reading. Also, I hope there will no more airport-escaping scenes in the next books. Maybe my expectation is too high, but I really think that the authors have not done a good job with this one.
