From an Amazon.com reviewer:
I must admit that I was intimidated for years by this novel. It sat on my shelf for ages, neglected in favor of "easier" books to read. Once I started it though, I couldn't put it down.
I generally read really quickly, but you really should take your time with every word of this novel. Otherwise you miss sentences like the following:
"If we had a keen vision and feeling of all ordinary human life, it would be like hearing the grass grow and the squirrel's heart beat, and we should die of that roar which lies on the other side of silence." !!!!!!!!!!! AMAZING.
Not to mention a lushly romantic plot that really tears you apart. I couldn't believe how breathless I was during the interactions of two of the main characters. Deeper messages aside, this was an emotional experience. I read Middlemarch like I read novels that will not be in print more than 10 years. So don't be intimidated by the density of the prose like I was!
