Writing Paranormal Romance - Character Creation

Paranormal Romance has two key characters - your main character and their love interest. But how do you write compelling characters when it comes to PNR?
First, you need to decide what type of supernatural your characters are and build up their backstory.  What is their life like? What challenges do they face? Remember that before they get together, your characters have lives and issues of their own. They are not just sitting around waiting for the other to show up!
While your characters will face obstacles in getting together, they will also face issues in their own separate lives that could impact their life together. For example, one character might be dealing with a hunter trying to kill them. The love interest could (and should) get caught up in that. Or perhaps one of them has been cursed and it will eventually kill them. How will that affect their love interest?
The way to answer these questions is to decide what kind of person they are. They need to have their own unique personalities and also be likeable and/or relatable. If not, the reader isn't going to root for them.
Before you start writing, create a brief profile for both characters in their individual lives - family, background, conflict etc. Then consider how they will work together. This is how we get our tropes such as grumpy/sunshine or enemies to lovers. 
Once you know your characters inside out, you can figure out exactly how they would react in any situation.

​Happy Writing!
