Suspense thriller that will keep you on edge!

"Tell No One" is a suspense thriller that does exactly what it says!  Dr. David Beck has had a very hard time getting back to life after the death of his wife - eight years to be exact... then he receives an e-mail from her
with a phrase that only the two of them know.  Mystery and intrigue follow, but who can he trust? 

I could not put this book down....  excellent reading for grades 9 - 12.
