As a reader I am gratified by well written books. However, as a writer I can be gratified by a badly written one. I know how uncharitable that sounds, sorry.
As a reader I read Sarah Waters's Affinity and was blown away by the writing and the narrative twist. As a writer, I've just read her more recent novel, The Night Watch and was greatly irritated, mostly by the narrative.
The story goes in reverse chronology starting with 1947, then 1945 and finally 1941 and I couldn't help wondering if this was nothing more than an attempt to make it more interesting. In the right order, it would have been a very unremarkable story indeed. The frustration was that we meet the characters at the end of their development arcs and, quite frankly, none of them were very likable. I wasn't so bothered about how they got to the positions they were in as how they would get out of them.
A good story is seamless, smooth and tight like a pair of silk stockings; the writing so good it is nearly invisible. The Night Watch, however, is a roughly knitted jumper that starts out full of holes and loose ends, then unravels with each section until the narrative threads end up in a jumbled heap.
It's good to know the masters of the art drop stitches from time to time, just like us apprentices.
