Potentially good but……
I think this is a book of two halves. The first all about a swimming club and its pool, the second about dementia. I am guessing the main feature of the pool is its imperfection, the supporting casts of swimmers are just not given a chance to develop their characters. The reader, well this reader anyway, is constantly wondering if anything is going to happen and when it does, it sort of doesn’t! The second, very loosely linked to the first part of the book is about dementia and seems to be very well observed or researched. Often moving and occasionally, like the first part, humorous. The saving grace for the book is that it is extremely well written.
