It's a chance to tell everyone what current book(s) are keeping you company when you're not posting on here or sitting solving puzzles. You can reccomend it, warn people off it, or just tell people. (I've had a couple of good 'recommendations' over on DVP during PM conversations).
I don't know about anyone else, but I quite often have 2 or 3 books on the go at the same time: one by the bed, one in the car (for the 'pick me up at..' requests that never quite work right), and usually one at work as well. [Working in a variety of libraries is terrible for me as I'm always seeing new books I want to read

I have a word processing file on the works computer called BookList, and I add all the things I'm looking to read (then use the library system to see which of our 20+ branch libraries has them)

So - my current reading:
Just finished The 39 Clues (which I grabbed from the library shelf thanks to katsmom) - now I want to sign up for the website and play the game

Snakehead - the latest Anthony Horowitz 'Alex Rider' book - Good action, and easy reading.
The Way of the Shadows - Brent Weeks - this is the first of a trilogy that my mate bought me the set of for Christmas. Plots, Magic Users, and a couple assassin anti-heros. Very powerful characters and good action.

Anyone else?
