the reason why another character chose the path they did. i believe it is a brilliant skill to be able to use subsidiary characters more as tools rather than personalities in their own right, as a way of finding out more about someone else.
for me the book was a brilliant read, one i found difficult to put down, as i was always wondering and wanting to find out… would they find each other? what happened to them? how were these people linked? everyone enjoyed the book and it was an excellent story for raising discussion points, such as why certain characters were included, what was the significance of that comment
