First, you have to come up with a world to build, some characters with a common thread or one character with a whole lot to him or her. I decided to add a little paranormal flare to my series by setting in a spiritualist community and making my heroines witches. Not point-and-shoot witches, like Samantha Stevens, but real live, modern day witches. They are members of the same coven, and each has her own special talent. And her own suspenseful plot to meander through.
So I worked, I researched, and I even attended a few witch circles. And finally, I've released book one and two of The Witches of Freedom Moon—Hidden Magic and Killer Magic. But I wonder how the reading public will take to my modern version of witches. They do spells, but they can't wiggle their nose to make things happen. They are spiritual—not demonic. They worship nature and embody all that contemporary pagans do. I hope that realism isn't off-putting for anyone expecting Sabrina the Teenage Witch.
But I digress. The series has been challenging for me, mostly because I have ADD! One book captures my attention, and then one day, another spark of an idea steals it away! Although I've planned the series as three books, I don't know when I will get to book 3. Unless of course, a gazillion people read the first two books and beg me to write the third;-)
I seriously admire anyone who can write series well, particularly those with more than three books in them. Many of those very talented series writers are right here at NYUS! Hats off to you if you can capture not only your own attention for multiple books, but that of your fans. I sure hope I can follow in your footsteps.
