Magic Dark, Magic Divine by A J Locke

Falling asleep for almost 300 years was never part of Pennrae's plan.

Of course, when you're a mercenary with magical abilities and defy a spellbinding prophecy...bad stuff happens.

Now, magic is long gone from the world. So Penn works as a karate instructor, trying very hard to dodge her hot, flirty, and super annoying colleague, Callan. All is well until a Jigori - a nightmarish magic-eating monster - shows up at a New York City street fair, forcing Penn to use her Shaper magic, which allows her to transform wood and metal into deadly weapons.

Now, the Jigori's master has her scent, and their eye on stealing her 300 years of life. If they succeed, Penn succumbs to centuries of sleep again, and magic will be unleashed on a completely unprepared world.

And to add to her ridiculously complicated life, something isn't quite right with Callan. Which she could figure out if it weren't for that evil, apocalyptic plot she's trying to stop. But Penn may not have a choice - Callan could be the secret weapon she needs to save the world...
