I am an avid fan of David Weber since reading his Honor Harrington series and his Horse Stealer fantasy series. Since those early days I read everything else too and he is rarely off top form. I am not going to repeat the synopsis because you can read what's above, but I think it's worth reading my comments below.
I adored this smart, competent, tough, young, feisty, female protagonist, Alicia, originally created in the novel Path of the Fury (POTF), and I was highly excited by the idea of a prequel. NEW readers of Alicia will love this book as it's wonderfully crafted, humorous, realistic and empathic characterisation and is fantastically plotted. However, readers of POTF might not be so delighted, hence 4 stars not 5.
The problem is that while I LOVED finding out the early days of the "larva" turning into a "wasp" (military terms used in the book), BUT I became quickly frustrated as Weber seemed to "tease" us with quick glimpses of parts of her early life, which I wanted to explore more of, but he'd quickly then race on months later or into the next major section of her life without regard for the transition bit... I know it keeps the story moving, but it just seemed a bit clumsy and jarring as Weber is usually so smooth at creating a sense of passing of time that it seems natural. I just don't feel that we've really scratched beyond the surface of this character by this backtracking. Not that Weber's prose was bad by any means, it just that when Weber had backtracked before in the Honorverse, his short stories provided more details and his novels don't keep skipping over so much time between chapters.
I guess I wish Weber had made more of the prequel. Perhaps releasing them as a series of short stories, rather than pushing it as part of a re-launch of a book. Some of the new parts of the book seem like small novellas gravitated together by poor cohesion strategies, which is uncharacteristic of my favourite author. I love this character almost as much as Honor and I was just disappointed not more was made of her as the Honorverse. Write more about Alicia please David, you haven't nearly satisfied me!
