I made it through House of Leaves, It did take me a while, because I had to read it a bit at a time. it was certainly not a book that I had trouble putting down.
Of course, I generally do not read to think. I read to be entertained. (there are exceptions, of course, I try to force at least one 'intelligent' novel on myself a month) This book was right on the cusp for me, and while I don't mind the thinky stuff, it will not hold my attention as well as the non-thinky books.
I enjoyed it. To me it seemed almost like not only was there a fourth wall AND an unreliable narrator, but there was also an implied fifth wall (the minotaur as threat to reader), whatever the heck that means. I am a complete sucker for a crossover of any kind, and this one was close enough for me to think of it as such. THe other thing I liked was that, by complete coincidence, several of the OTHER books I was reading at the time either had something in common with HOL, or with each other. Being the creepiness lover that I am, I loved that, in a goosebumps up the arms sort of way.
OR, on the other hand, I wanted to throw against the wall.... a bittersweet moment, as it was the library's copy, and while I was denied the satisfaction of book abuse, I was glad it was not my money that had purchased it.
