FIRST NEW HONOR HARRINGTON NOVEL IN FIVE YEARS! New York Times, USA Today, Wall Street Journal and international bestselling phenomenon David Weber delivers book #19 in the multiple New York Times best-selling Honor Harrington series, the first new Honor Harrington novel since 2013’s Shadow of Freedom.

This arrived on Wednesday and I was done on Friday. One of the first in a while books that was hard to put down in the series.
Heads and shoulders above the last few of the series and I can happy to see it end on a high note.
This book nicely completes the run of 19 books in the Honor Harrington series (although there are still many spinoffs) and is recommended for anyone that found any of the books interesting.
