Book store missing on iOS 12

I assume you've checked to see if you've hidden the iBookstore by setting Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps > iBooks 'off' (it used to be Settings > General > Restrictions on iOS 11 and below) ?

THANK YOU!!!

I don’t know why they don’t mention this easy fix in their ‘official’ troubleshooting post...I know it was some obscure toggle for the last version as well, but you’re the first after 2 hours of googling to mention it for 12. Emperor Penguin, more like!

Books Store is in the Books app

I have no problem accessing the Books Store in my Books app (iOS 12).

I had the same issue. Thanks to King_Penguin. Already solved.
