The Eternal War — Alex Scarrow

Continuing the heart-pounding, time-bending action of the TimeRiders series, The Eternal War brings readers back to a pivotal time period in American history: the Civil War. Only this alternate history is one where a young Abraham Lincoln has somehow followed Liam into the present from 1831, and the entire course of American history has changed. If the TimeRiders can't return Lincoln to the past, the country could be trapped in a dangerous state of never-ending civil war. Can Maddy persuade two colonels on either side of no man's land to cease fire long enough to save the future?
