Timothy Zahn returns with a new trilogy that looks at Thrawn’s Canon origins within the Chiss Ascendancy. Chaos Rising opens beyond the galaxy’s border in the Unknown Regions where the Chiss and the Nine Ruling families reside. When a mysterious enemy attacks the Chiss capital, the Ascendancy deploys a brilliant young officer named Thrawn to expose the assailant. Alongside an ex-Skywalker searching for purpose and a young navigator discovering her own, Thrawn attempts to save his beloved Ascendancy as its leaders find their new Captain may be much more trouble than they had ever imagined.
