Zyda is one of the most deadly beings in Terra Vox. She contains the lethal substance Vercilon and with a small slip-up she could destroy an entire city. Everyone in Terra Vox is born with a power. The range of powers are extreme, from changing eye colors to being able to blow things up with just a thought. Because of this, people with dangerous powers are ordered to go before the royal family and are often put to death. But Zyda's parents saved her and kept her power a secret. Still, her life is anything but fun; lies keep her alive, but she doesn't really live. Every time she loses control of her emotions, she burns away and heals herself simultaneously. Every day is a struggle... Until she meets Tristan, who finds out about her secret and agrees to keep it. They quickly become best friends and fall in love, but apparently Tristan is living off of lies as well. He's hiding something that turns her family's world upside down. Meanwhile, Zyda's sister Abby is sicker than anyone realizes, and when she reaches a point of no return, Zyda must save her, drawing unneeded attention to herself and making her own deteriorating state more difficult to keep under control. But none of that is enough for the world of Terra Vox, because when the royal family invites all of the most powerful people to the castle, Zyda learns she must help the people who would have her dead.
