War veteran Clavain and a ragtag group of refugees have fled into hiding. Their leadership is faltering, and their situation is growing more desperate. But their little colony has just received an unexpected visitor: an avenging angel with the power to lead mankind to safety -- or draw down its darkest enemy.And as she leads them to an apparently insignificant moon light-years away, it begins to dawn on Clavain and his companions that to beat one enemy, it may be necessary to forge an alliance with something much worse . . ."Absolution Gap is a good as it gets, and should solidify Alastair Reynolds' reputation as one of the best hard SF writers in the field." -- SF Site
