Book Removed from Library and from Store

Hello,

First time poster here and I've got a situation that concerns me a little. It looks like a book I bought from Apple Books was removed from the store and thus removed from my Library. I had to do a little searching to dig up the Apple receipt. But this isn't cool, I know that it is only a couple bucks lost but how is it that I buy a book and it's gone and I can't download it to read?

I attached the receipt. If you were to look up the book on the store, you'd see there are other versions for sale but just not this version with the same book cover. Obviously this worries me a bit that if books are taken off the service then you lose your access to read them even after you buy them.

I'm looking to see if this has ever been a problem for anyone else before and could I request a refund?

Thanks for the help.
