Zombie, Ohio A Tale of the Undead - Scott Kenemore is also a good one

I'm surprised nobody has mentioned Max Brooks World War Z when it comes to zombie books its a pretty great one! Also the zombie survival guide by him is good tho I guess that one is more of a how too

[Baldacci, Child & Coben; Any thoughts?]

I've read the first five or so of Lee Child's Reacher books and really enjoyed those especially the Killing Floor, after those I wanted to mix it up a bit and find another main character so read a couple Michael Connolly ones that I also liked a lot (A couple of the Michael Haller ones and The Scarecrow). And recently I have read David Baldacci's True Blue (started well but ended poorly) and The Winner which I loved. I have been hearing a lot of praise for Harlan Coben so I figured I would try a couple of his books next. Any suggestions on whether to start with his stand alone books or dive into the series he does?
