A book is not just a collection of words, it is a perception portrayed on blank sheets. You know, getting you the feelings of blowing winds and rains and sun and flowers around, the smiles, the tears, the notional links with the characters and make them all alive, while you read. And that's sure as hell a gruelling task !
Read, read, read. Read everything - trash, classics, good and bad, and see how they do it. Just like a carpenter who works as an apprentice and studies the master. Read! You'll absorb it.
Then write. If it's good, you'll find out. If it's not, throw it out of the window.
