Maybe you need to try some different ones then? Reading isn't for everybody, but many people don't give it a proper chance. There is an absolute ton of shit literature out there, which is why I only ever choose my books via reccomendation. However I too have a vague imagination and have trouble picturing characters or settings - but I still love it anyway.
As for what Mitobunny said about The First Law series, I don't understand what he means about it being easier for people with bad mental imagery... But Abercrombie certainly is a fantastic author, and while his books start off pretty mediocre, they thankfully only ever increase in quality. Try renting the first book "The Blade Itself" from a library and giving it a shot!
