What is the author's style in Replay by Ken Grimwood?

Meaning itself is central to the themes of Replay. Jeff's experience of loss and unknowability is an experience of the meaninglessness of his existence, disconnected from other human beings. Pamela experiences a similar isolation, holding her experience as a secret that cannot be communicated. Both Pamela and Jeff attempt to communicate their experiences with others—Pamela though her films and art and Jeff through his books.
