I say rarefied, because I only have one, rather hefty, bookcase, and its contents are constantly being picked over, culled, shuffled, re-arranged but rarely ever dusted.
I'm forever trying to diminish numbers in order to make room for new favourites. There are some hard won battles going on constantly. And often a book might fail in a skirmish, only to be retrieved from the 'donate to charity' pile a few days later and returned to its former spot.
Thought you might like a look-see at what I consider my champions. In no particular order:

These books remain in my bookcase for a variety of reasons - mainly though it is because on some level the author has blown me away. It can be any one or a combination of factors. Creativity. World-building. An epic romance. Intricate plotting. Humorous. Kick butt (I so want to be her) Heroine.
Hopefully the war to stay in the bookcase will be a long, hard fought one, and I will reap the benefits of it daily.
May all your books be five star.
