Brilliant and such a fun read. Definitely a guilty pleasure. And definitely not to be taken 'seriously'.
As a reader, you come across books that are 'heavy', others that are 'light/fluff'. I love both types, as both are equally hard to write (and IMO lighter books are harder).
Charlaine Harris' books are definitely and meant to be part of the 'light' group. If you want to relax, switch off and have a bit of fun - these are for you!
Although I imagine everyone in the entire universe has read these books already - I highly recommend them to all, especially vampire fans.
My only thing is the back of this edition said 'move over bella. sookie stackhouse is here' - Now, its really really important to remember (especially twilight fans who believe this series is a twilight knockoff and have been quite harsh, especially in regards to Sookie's gift) that these books were published in 2001 and have won awards etc. so my recommendation to twilight fans is don't go in judging the book - sit back, relax and enjoy the ride because these books are such a yummy guilty pleasure!
So I'm giving them 4 moons!
