I bought this book impulsively in town and by the time I had to get off the bus heading home I was hooked. I had to run from the bus stop to my house so I wouldn't be tempted to stand in the street reading (thus looking ridiculous).
Overall, it's a good read but some scenes are particularly great. An original concept sets the scene for what is essentially a zombie fest. And from the zombie outbreak follows a whole variety of situations, encounters, twists and reveals. I don't think the characters are well developed but we certainly get to know the zombies, sorry... 'phone crazies'.
Before I delve in too deep and start dishing out spoilers I'll finish with this; If you're looking for something to spark your imagination and you like zombies, buy this book.
