Hello, Elle!
I don't know much more than you about the Indianapolis.
Maybe you heard it mentioned in the film "Jaws"?
They had just delivered vital parts for the Hiroshima bomb, very hush-hush.
The captain was unfairly blamed by the Navy for not zig-zagging to avoid torpedoes.
And he killed himself many years later.
That's all I know.
The other book is by Deric Longden, and I think/hope it is a humorous one, something like Miss Peckwitt's.
He and his wife go to live in Huddersfield and have a lot of cats.
I do not know either of the authors, but at one time I did not know Bill Bryson!
I am with EE, and find them reasonable to deal with.
Hope your daughter gets a satisfactory resolution.
