Folks at my work are trying to start an IRL book club that will meet about once a month. The organizer gave us a choice of 3 things that were on her TBR and the others picked Room - Emma Donoghue as the first selection (I voted for one of the other selections
I was a bit hesitant about Room and thought that the artifice of a 5-year-old narrator would quickly get tiresome. But surprisingly, even though the kid narrator worked the best for the first section and didn't quite feel right for some of the later sections once the wider world intruded, I enjoyed the whole book.
Things I had issues with after the spoiler tag
I didn't like the cliffhanger at the end of the 4th chapter when you aren't sure whether or not Ma survives her overdose
I also was surprised that Jack wasn't more agoraphobic and having more visible discomfort once there wasn't a roof over his head or rooms that were larger than Room (but maybe I've just been reading too much SF with former spaceship-dwellers being agoraphobic once they leave the ship.
