18's the fizzle

Stephanie Plum's adventures are going downhill since '10 big ones'.
The art of Evanovich has-been to happily drown her chick-lit style, implausible plot's characters and screaming inconsistencies in fast-paced, hilarious stories.
The operative sentence of the above extract is now, sadly, 'has-been'. The good yarn is now a big yawn.
Still, newcomers to the Plum's novels should read the first ten books, wich true-have entertainment value.
