I am horrendous with challenges with time limits. So thank goodness for projects like these - a great selection of award-winning books and no time limit! So far I've read only two Bookers in my lifetime (horrendous again!) but I will definitely be reading more. Looking forward to your thoughts.
Read the Nobels" which obviously is to read anything penned by Nobel Prize for Literature (and no time limit!) Maybe you'd like to add that to your own pile of challenges?
