From the dawn of the dinosaurs…to the Battle of Trafalgar…to the end of time itself…the first century-spanning adventure of Ivar, Timewalker starts here! At this very moment in Geneva, Switzerland, history is being made. A thousand meters underground inside the Large Hadron Collider, researcher Neela Sethi is about to discover time travel – and jeopardize her life in the process. But she doesn't know that yet. Ten minutes from now, every deadbeat chrononaut, wannabe conqueror, and misguided protector of the timestream will be banging down her door. Good thing that the legendary Ivar, Timewalker, got there first…right? Now it's down to history's most jaded, most tempestuous time traveler to stop the worst of everything that is, was, and will be…before time runs out!

New York Times best-selling creators Fred Van Lente (Archer & Armstrong, Amazing Spider-Man) and Clayton Henry (Harbinger, Incredible Hercules) begin a clock-stopping odyssey into the distant past, far future, and every moment in between right here with the first volume of Valiant's lates­t epic.
