Can someone check my linking?

[☕ Lachgas ♿]

While feeding my ebook reader I noticed the Niven has an ACE (and I thought it's a new book - damn) and therefore entered both.
I tried to link them to each other but if I click on the links just nothing happens https://www.goodreads.com/book/show/3... - so is that just me and my PC or did I something wrong in creating the link?

Unclickable just for me or anybody?

There was an error in both links. They should be working now.

Thanks a lot!!

What did I wrong? (just to avoid it next time)

edit: ah thought of looking into log - the a shouldn't get closing tag and the href doesn't need one at all

and " around the URL

hm - tested that (accidentially) but the " don't seem to be necessary
does work without them https://www.goodreads.com/book/show/3...
