Oh I love Nelson DeMille's books! I have read Plum Island a few times, Charm School twice and Lions Game twice.
Other rereads (t least all the ones I can think of off the top of my head):
Rebecca - Daphne Du Maurier
Jane Eyre - Charlotte Bronte
Tell No One - Harlan Coben
Pompeii - Robert Harris
Archangel - Robert Harris
Gorky Park - Martin Cruz Smith
Want to reread soon (but means getting in the loft and sifting through a dozen boxes of books that I have stowed away because of lack of book shelf space so probably won't happe anytime soon ) :
Behind the Scenes at the Museum - Kate Atkinson
Human Croquet - Kate Atkinson
The Wilt series by Tom Sharpe
