I've been reasonably ambitious with my first attempt at a novel. I'm five chapters and about 15,000 words in. The story is a re-telling of various elements of the life of the world's oldest man, in the first person. I've redrafted and totally re-jigged the whole things many times now and am beginning to be happy with the way the story is developing. The one thing I am concerned with is the notion that a reader can stay engaged, within the world of the novel, despite potentially many years passing by between chapters. For example, Chapter 1 begins with a 10 year old protagonist, by Chapter 5 he will be nearly 16. Bigger leaps will occur as I move forward with the story. Appreciate any views?
