The first thing I thought when I saw David Weber's new novel At All Costs was "Huh, he finally ran out of titles with 'Honor' in them." (Six of the eleven novels featuring Honor Harrington, plus three of the four short story anthologies set in the same universe, have 'Honor' in their titles.) It took me until the second novel in the series before I really got into the saga of Honor Harrington and the Royal Navy of the Star Kingdom of Manticore, but I am now sufficiently addicted that I had to keep reading this new one, despite the flaws I encountered in it.
It's always the characters that are interesting in a novel, and Weber has, over the course of the series, introduced a great number of them. Harrington herself, her family members, fellow Navy members and friends, Queen Elizabeth III of Manticore, Protector Benjamin Mayhew of Grayson, all on one side of Manticore's ongoing war with the planets making up the Republic of Haven, but the Havenites are seen as people too. President Eloise Pritchard and Secretary of War Thomas Theisman, for example, are a Havenite government the reader can sympathize with, unlike some in the earlier books, and both sides would really rather not be fighting anymore -- yet the number of battles in space in this book seems to exceed that of any previous installment. Or maybe it just seemed that way because the battles did not draw me in at all; they were near-endless strings of numbers, of how many missile pods this side can launch and how far they each have to travel and how much defense the other side can muster. It became a series of word problems out of a math textbook, and frankly I didn't want to have to work them out, so I found myself skimming the battles for dialogue that would keep me up to date on what was happening without being so boring.
However, when no one was actively in battle, the book was fascinating. Not only the political ins and outs of Manticore, Haven, and other organizations trying to influence events, but also what was going on in Honor's personal life kept the story moving and the reader interested. This wouldn't be the place to start reading the series -- it's much too complex at this point -- but it continues to be a series generally worth reading.
