Typo?

Either: okumuþ olmam

Or: You ought

 I might read this novel.  (No need for the "to")

 her ne kadar zor olsa da: this is better translated as "no matter how hard it is"

No matter how hard it is, I will read this novel

 You could have read this novel

 It is better English grammar to say "I wish I had read this novel"

 Advice is a noun.

Advise is the verb you want

(PS a lot of native speakers get this wrong! It is like practice and practise.)
