Warrior of the Divine Sword Series

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. 

All Pennrae wanted to do was to help. Now she's found herself in a world that's been instantaneously transformed by magic . . . that she brought back. She's gone from a simple karate instructor to an instant celebrity—and she hates it. Fortunately, she has her friends, her beloved magic companion, and one ridiculously hot boyfriend. But a sudden, unprompted attack in broad daylight is about to make Penn's life even more complicated. An ancient forest guardian known as a Kiabi—a warrior of magic and almost impossible to defeat—has marked Penn to die.
