Rock, Magic, and Destiny

Nyssa Thorne has spent most of her life surrounded by mysteries.
Found alone after the deaths of parents she barely remembers and raised by the Blake family, Nyssa learned long ago that family isn't always determined by blood. She found hers in her adoptive sister Daphne and, eventually, in the mismatched group of mystery solvers she would come to love more than anything.
Mystery Inc. is her family.
But even they don't know everything about her.
Behind the quiet smiles, extraordinary intelligence, and seemingly endless collection of talents, Nyssa hides a secret known only by Daphne, Shaggy, and Scooby-Doo.
Nyssa Thorne is a witch.
For years, she has secretly studied the spellbooks and strange artifacts left behind by her biological mother, mastering the mysterious purple magic she inherited from a family she knows almost nothing about.
There is only one mystery she's never been able to solve.
The small blue lightning bolt that has marked her ribs for as long as she can remember.
When Mystery Inc.'s latest adventure brings them to KISS World, Nyssa expects another mystery filled with elaborate costumes, impossible suspects, and plenty of Scooby Snacks.
She doesn't expect her magic to recognize a place she's never visited.
She doesn't expect secrets surrounding her dead parents to lead beyond Earth itself.
And she certainly doesn't expect the mysterious mark she's carried her entire life to suddenly begin glowing the moment she meets the Spaceman.
Nyssa is about to discover that monsters aren't always people wearing masks.
Magic isn't limited to Earth.
Her parents came from another dimension.
And the legendary warrior standing before her isn't simply a member of KISS.
He's her soulmate.
As an ancient evil threatens two worlds, Nyssa must uncover the truth about her forgotten heritage, master powers greater than she ever knew she possessed, and decide whether she's ready to trust the one man fate has bound to her soul.

I only own my oc and her plot.
