The Awakening — Amanda Steel

The second short novel in a series of three.
Hope has been under a sleeping curse for ten years. Now she's about to wake up and discover how different the world is from the one she knew before. Witches out number humans. While many humans have magic, it's not enough to defeat the witches. That job falls to Hope and her twin brother Ben, but neither of them are sure how they're supposed to fulfil their destiny.
