Time Shift Trilogy

When 15-year-old twins Malcolm and Valentine Gilbert moved to a new town, they never imagined that the old house across the street could bring them so much trouble. Inside the old house, a secret machine with the power to pierce time has reawakened. Meanwhile, lightning storms are breaking out all over town. They're getting worse every week, and seem to enjoy striking kids who just want to pass science class and mind their own business. When Malcolm and Valentine discover a connection between the house and the storms, their situation goes from mysterious to crazy-stupid dangerous. Someone is controlling the great machine, and their purpose is nearly complete. In a race against time, the twins must uncover the chilling plan, the mastermind behind it, and the force that's driving the deadly storms. They'll hunt a powerful enemy that threatens their town's existence, and the only clues are written in the sky.

It's summer in Emmett's Bluff, and the ice is spreading. Six months after confronting an enemy from the future, Malcolm and Valentine Gilbert have returned to their normal teenage lives. Or, they've tried to. During the battle to save their town, a mysterious force awoke inside the twins. Time calls to them, and it's growing too strong to be ignored. When warriors from a mysterious ancient kingdom appear, they bring warnings of an unstoppable foe-one whose control of the ice is powered by Time itself. But ice is far more than the Black Tempest's signature. As the twins uncover the truth behind it, they realize their town is only the beginning. If the Black Tempest is not stopped here, his corruption will threaten the very course of history. As cold advances and doom draws near, the twins' only hope lies in learning to wield Time itself, and in trusting their strange new friends-even if those friends have secrets of their own. When warriors from a mysterious ancient kingdom appear, they warn teenage twins Malcolm and Valentine Gilbert about an unstoppable foe.

The timeline is burning. No one knows why. Teenage twins Malcolm and Valentine Gilbert have defeated doomsday machines, ice monsters, and time-traveling supervillains. Yet their full potential remains out of reach. The Chrona is elusive, and without her guidance they struggle to grow in their abilities and to choose the course of their lives. When an enemy invades from the future, he brands the twins as war criminals. Blaming the twins' future selves for attacks on his people, he plans to destroy them before they can strike. But the flames of his vengeance don't just threaten Malcolm and Valentine-they threaten the entire world. As Everwatch arrives to protect the timeline, the forces of past and future collide in the present. Amidst a war between ages, the twins must uncover the real truth about themselves, their accuser, and the secrets that brought him to their town. At all costs, they must unlock their true power before the enemy breaks the timeline completely. If they fail, it could mean the end of Time itself.
