Is this okay to do?

So I read a book a few months back that gave me an idea on an episode story. Am I allowed to do this, I read the copyright policy but it confuses me a little.

Of course I’m going to use different characters and try and use a different plot, but the idea is the same.

I can give the plot if it helps.

It’s basically about a world where love is considered a disease, but this girl like falls in love. And runs away with the person she loves etc. the original book is called delirium, I was just wondering if I could make a episode story about love being a disease, but having a different storyline and characters.

I’m not sure… You may want to contact episode…
