Guardians of Porthaven
(Book)

"On his fifteenth birthday, Malcolm Gravenhurst is preparing to take on the mantle of Guardian, like many Gravenhursts before him. The Guardians are tasked with defending the city of Porthaven, and his family is the only one to possess the superpowers necessary to battle the frequent alien invasions of robotic klek. But power has brought the Gravenhursts more than just responsibility--it has also brought them fame and wealth. When Malcolm meets some teens living and working in secret, he learns that underneath their heroic facade, the Gravenhurst family is hiding some very dark secrets. With the threat of annihilation on the horizon, soon Malcolm must choose between family loyalty and doing the right thing."--,Provided by publisher.
