Well, is it?   They hype, the fuss, the late night book sales?
Is the story worthy of all this drama?
Does the plot and character development warrant all the media attention?

Sure.

And how do I know?   I have only read the last chapter at about 1 a.m., but the smile on Ash's face when she saw her copy, purchased from Tesco in Trowbridge just after midnight by big Mike, said it all.

When she's finished I might even get to read the rest.
