Not sure if this is the correct thread for this since these books are considered non-fiction, biographical,
and historical fiction all rolled into one.
But today only* all of James Herriot's (US version) books are on sale for $2.99 each - in the US at least.
They are couponable at kobo as well.
I grew up reading these and highly recommend them.
