Trail of the Spellmans by Lisa Lutz. Read by Christina Moore.

This is the 5th installment of The Spellman Files (released in 2007) and the series is getting tired. I didn't laugh out loud while listening to the audiobook, although I did cringe with Christina Moore's version of Rae's  and Isabel's voices in places.  Funny how the accents and obnoxious-ness changed throughout the reading.

Isabel is still in a love/hate relationship with her family and trying to stall herself from growing up in her relationship with Henry.  Her arrested development didn't seem to be funny in this book--just sad.  Rae is all grown up now, too--her antics weren't as extreme as usual and the entire family just seemed to be growing up and apart.  I felt like this book was the last in the series--but I know that #6 The Last Word has already been published.  I think I'll do the book justice and read it in print form to see if I find it funnier.
