Princeps' Fury

In book five of the six book series, Tavi travels to Canea, Gaius Sextus sends Bernard and Amara on a dangerous mission deep in vord territory, and Isana is up north on an impossible peace mission. Once this book gets going it's tough to put down. There's a surprising finish but at the same time this book lays a lot of groundwork for the big finish. I'm reading book six right now. Love this series.
