The Lighthouse reminded me slightly of Julian Barnes, The Sense of an Ending, as both novels are about memory and retrospection. Though I think Barnes novel has the edge.
Futh is a bland, forgettable man, so it is to Alison Moore's credit that she manges to produce a readable book about a boring person. Although sometimes Moore is in danger of been boring herself, particularly when she repeats the same story over again. I know she does this as it mirrors how memory works, we often relive important moments, and our recollections from early childhood are few, but I don't really want to read about the same event 3 or 4 times in the space of 192 pages.
Ester is more interesting character than Futh, and I wish more time had been devoted to her. I didn't really feel her motivation for her self-destructive behaviour was explored in enough depth.
There also seemed to be too many coincidences in the novel, which is often the case I feel when novels include characters that have interconnecting lives. Both Futh and Ester have unsuccessful marriages that are marred by infidelities and both have a weird obsession with a bottle of perfume shaped like a lighthouse.
Like I said, its a very short novel, so wouldn't take up much of your time. It might be worth a read if you are interested in the literary devices authors uses to try and convey concepts of memory and remembering.
