Alien Blood — Chris Archer

In the second book of this middle grade sci-fi series, a teen survives a near-death experience and gains alien powers that make her a killer's target.
 
Ashley Rose might be the world's biggest movie buff, but when her life becomes a supernatural thriller, she'd do anything to go to back to being an ordinary teenager at Metier Junior High. Only Ashley is anything but ordinary. On the night of her thirteenth birthday, she falls through the ice into the town's reservoir, the one where UFO sightings allegedly happen. Not only does Ashley survive the frigid water against all odds, but she suddenly has powers beyond her wildest imaginings. Her supersonic hearing comes in handy at school, and the fact that she can now breathe underwater makes her the new star of the swim team. But her powers come with a price, because now that Ashley has alien blood, she also has extraterrestrial enemies who will stop at nothing to kill her.
