And it was on these fields of battle that the seeds of humanity's eventual destruction were sown. solation takes us back to the front lines of this war, a time when mankind's ambition far outstripped its foresight. Heron, a newly trained Partial soldier who specializes in infiltration, is sent on a mission deep behind enemy lines. What she discovers there has far-reaching implications--not only for the Isolation War, but for Partials and humans alike long after this war is over.
