Is your feature request related to a problem? Please describe.

Book thematics are shown on the scrollable book list but aren't on the book page. I thought maybe i could see the whole list of thematics it fell into but i couldn't.

Describe the solution you'd like

Show the categories/thematics on the book page.

How will you/everyone benefit from this feature?

Seeing some information on the book list and not on the book page is misleading, so people won't be mislead.

Additional context

At first i thought these categories might be explorable, might be available filters for my search. Couldn't find if they were, but ran into this issue nonetheless!
