I had just read Prudence which had somewhat spoiled this book to me as it include part of the big reveal - which meant that I found it hard to get myself to finish it. Otherwise it was as crazy and action packed as much of the rest of the series. 
 This series work a lot better for me as audiobooks though than as regular books. The humor just works better read out loud than in print. 
 On another note there seem to be a pregnancy theme in the books I pick up right now... I am not sure why - it is not something I seek out.
