If you like reading about self absorbed characters this isn't the book for you. I will not be recommending it. The writer is one to watch and if there are other books of his worth reading give it a shot but check out what you're buying. Not some &#34;greatest hits&#34; crap. I'm sure he has some redeeming qualities however it's hard to root for. Sorry author. It's been an agonizing 2 months having waited till now only to want my 2.99 back.

What a great, simple little device! It holds my iPod Nano perfectly. My phone fits and I can fit it in there so it's super handy! Great price for such an incredibly useful item. A must have if you're into running.
