For some reason I tend to shy away from the BIG books, those being the books that rountinely make best of lists, fill the limited space in book review columns, and can generally be purchased at stores that also sell cashews and lube. I don't know if my aversion to widely-praised books can be simply diagnosed as hipsterism, or if there's something more sinister at play. But none of that matters, as I recently read one such department store paperback, Room by Emma Donoghue, and I really, really liked it.
