Thriller based around the National Security Agency's fiendishly expensive code-breaking machine and the mysterious email that can't be cracked.

Dan Brown is such a dreadful writer, yet this is the second of his books I've read and it has the same page-turning quality as The Da Vinci Code! I'm not quite sure how he does it because the quality of the writing is really appallingly groan-makingly cheesy, but his knack of leaving each short chapter on a cliff-hanger had me racing through this in a couple of hours, despite its size.

I've passed this on to my Mum, Herrgirl.

Thanks, it'll go on Mt TBR for a while!

Another pacy, against the clock thriller from Dan Brown,which I enjoyed although I didn't understand a great deal of the technical stuff and jargon.

Returning this to chelseagirl,as her other half, zb, may want to read it.

Back with me for a while now, many thanks.

RELEASE NOTES:

Set for a wild release in Oxford unless zb wants to hang on to it!
