5 stars for the last book and the series overall. Fun and witty and utterly enjoyable reads. Quite sad this is the last one but glad Carringer is stopping on a high note and not after 11 billionity books. 
 I would LOVE to see a Biffy stand alone novel, he was really quite the star for me in this one. 
 So many awesome quotes in this one, I made much use of the kindle bookmark feature :)
