Goddess Rising by Sharilyn Skye

Life has a funny way.

Random assassination and failed kidnapping attempts aside, twenty-five years have passed in relative peace since Lara Hennessey exploded into the supernatural world.
But that fragile peace ends when the entity that should most fiercely protect her decides to own Lara’s ever-growing magic instead, and if they can’t? They’ll see her dead. Still, if they fail, there’s always someone willing to try harder, and now Lara has to decide what she is willing to become and what she is not.
Add in recalcitrant children, an overprotective mate, and organizations set to discover her secrets at any cost, and what this Goddess Rising needs is a cup of coffee and a Carolina sunset. She has to survive to see it.
