Chaos (Tessa Avery #1) by Lucy Roy

For most girls at eighteen, life is just beginning: graduation, college, getting their own place. Unlike them, however, I’ve trained my whole life to be an Ischyra, an immortal soldier of the Olympian gods, and when high school ends, I’m going to Olympus to face my destiny, leaving all that I know behind. I’m a nervous wreck, of course, but making the transition from mortal to immortal, not to mention finding out what my affinity will be, has me over the moon. Finally, I’ll be tasting what I was born for. But not all is a bed of roses. Meeting the gods and the grueling training is nothing compared to the nightmares I’ve been having. Controlling my newly awakened powers is more of a struggle than I'd anticipated. Add to the mix a hot guy who I can’t make heads or tails of. And if that wasn’t enough, a bunch of the Titans who were defeated thousands of years ago have begun to gather forces, hoping to retake Olympus for their own. As an Ischyra, my duty is to protect Earth from those who would seek to harm it, but first I have to get through my training year. Yet as my powers start to take on a mind of their own, I begin to realize the gods might have other plans in store.
