Spirit of Fire - Spirit of Fire, #1

Seventeen-year-old Jade Taylor and her twin brother Jack are used to getting into a spot of trouble, but almost impossible things have been happening lately and everyone knows that misbehaving teens are no way near the worst problems that the police have to deal with. After all, what about the fields of crops that spontaneously combust for no reason? And what do you do with the hundreds of people that are being contained because they can command fire to erupt from their fingertips?With the police quickly whisking away evidence of these occurrences from the public eye, many people are oblivious to the danger that is all around them.
But Jade's curiosity leads her to carry out a spot of detective work. Yet her brother's biggest concern is making Elliot-the guy who preyed on their vulnerable younger sister-pay for his actions, something which Jade is unwillingly roped into.
