Resistance (The Variant Series, #2) - The Variant Series, #2

Alexandra Parker might be the most powerful Variant the world has ever seen-but even that won't get her out of finishing her junior year of high school. The challenge of keeping her abilities under wraps during class is daunting enough, but throw one surly, sandy-haired Jumper into the mix, and things can get downright complicated. Declan's new job? Watch over Alex while she's at school and do everything in his power to keep her from losing control.
But as sparks of every kind begin flying between Alex and her new bodyguard, she's left feeling more unstable than ever. When avoiding her abilities results in a surprise visit from her parents' killer, Alex's worlds collide with a bang that nearly levels Bay View High. With her freedom now squarely in the Agency's crosshairs, Alex will be faced with the fight of her life... and a decision that could forever alter the course of her destiny.
