Ironhand

This is an okay book written by Charlie Fletcher. While on a school trip, outcast George Chapman accidently awoke an ancient evil. Now, the statues of London have come to life, and after his last adventure, young George discovers that his friends have been captured. However, when George notices stone, marble, and bronze veins growing out of his hands, he learns that unless he completes three ancient challenges, the veins will kill him. This is the second book in The Stoneheart Trilogy.
