Simultaneous Reading

I can't seem to just read one book at a time. I get four or five going simultaneously and it sometimes seems like it takes forever to get through one - though I sometimes have spurts where the finishing of four or five books happens nearly simultaneously. So, as I continue to read Alex Ross' The Rest Is Noise (loving it) and Don DiLillo's Underworld (really enjoying it as, on pg. 350, I am approaching the half-way point), I've just added Cormac McCarthy's The Road. Winner of the Pulitzer Prize, I just can't resist apocalyptic fiction. Maybe I'll finish one of them by the end of February? I do have to say that reading Miss Liberty's twittering about all the reading she's been doing has been inspiring. But there are still only so many hours in a day and so very little I can devote to my love of reading.
