Room by Emma Donoghue starts by introducing us to five year old Jack and his Ma. Ma has been held captive by Old Nick since she was nineteen. Ma has protected Jack from Old Nick but Room is all that Jack knows of life, he had never seen the outside world and doesn't even believe that the outside is real. 
 Room is told by the perspective of five year old Jack which while unique can get a little irritating at times. The plot being told by Jack does have downsides such as with Jack being five he misses crucial parts to the plot because Jack is focused on other things, he's five and whilst this is forgivable it can get annoying. 
 The plot is well structured, you can split the novel into two parts. The first being where there in Room and going about day to day life. You can see a mother whose trying to get over her captivity and raise her son as normally as possible with the example of his lessons, the fact she tries to get him to do much more than just watch TV all day, the fact she sets out a routine for him and tries to save him from the gory details of her life. The mother does a fantastic job of shielding Jack but you can also see the points where her situations gets the best of her and she recedes to her mind for the day. The second part is where Jack escapes Room, you see a boy getting to know the outside world for the first time, a mother who finds herself struggling to deal with finally being free because the world has moved on and she's trying to return to her old life and she can't because life has moved on in the years she disappeared.
