THE LAST ADVENTURE OF CONSTANCE VERITY

Constance Verity is a little bit Nancy Drew, John Carter and Doc Savage
all rolled into one: she's fought aliens, vampires, and dinosaurs, and
travelled to the edge of the universe and beginning of time—but all she
really wants at thirty-five is a cubicle, standing takeout order and
boring boyfriend, if only her fairy godmother and destiny would stop
messing with her plans

Constance Verity has been saving the world since she was seven and she's sick of it, so she sets off on one last adventure to reset her
destiny and become the one thing she's never been: ordinary.
From the time she was granted a wish at birth by her fairy godmother, Constance Verity has become the world's great adventurer.
She is a master of martial arts, a keen detective, and possesses a collection of strange artifacts. But now, twenty-eight years later, all
she wants is to work in an office and date a nice, normal guy. And she thinks she's come up with a way out. The only problem is that saving the world is Constance's destiny. She's great at it, and there are forces at work to make sure she stays in the job.
Then again, it's also her destiny to have a glorious death.
