The Peacemakers (Earth Book 2)

Maggie Winstone is not your ordinary soccer mom. She's an alien, living and hiding on Earth; hiding from the ones who want her rare powers, and that of her children. She stayed hidden for years, but is unforeseeably thrust in the spotlight, when she prevents a teenage suicide attempt. After her true identity is discovered, and her daughter is kidnapped, Maggie decides she will do whatever it takes to get her daughter back, and stop her hunters from destroying the Earth, and her home planet of Ceron. She must bring peace, even if that means becoming one of them.
