This is only the 3rd novel by Julie Otsuka.
Short. In fact, I’d call it two novellas not particularly related to one another.
The 1st a very original and wonderful tale about the people who use a local community pool.
Swimmers.
Almost magic realism.
“In our ‘real lives,’” Otsuka writes, “we are overeaters, underachievers, dog walkers, cross-dressers, compulsive knitters (Just one more row), secret hoarders, minor poets, trailing spouses, twins, vegans, ‘Mom,’… .”
But once in the water, swimmers are only “one of three things: fast-lane people, medium-lane people or the slow.”
It reminded me of my days in the Brainsport Running Club.
Once having changed out of work clothes, people group into entirely new castes based on running ability.

The second half of the book — “Belavista” — finds Alice in a long-term memory residence by this name.
While very insightful into life (prison?) in a care facility, I did not enjoy Belavista as much as the first half.
Otsuka is obviously an excellent writer.
I’ll be reading her two earlier books, as well.
