Get started in the Honorverse with the free "On Basilisk Station [Kindle Edition]" from David Weber/Baen, now available on Amazon
I'm currently rereading this series and am enjoying is just as much as the first (couple?) time(s). Get started (and kiss your time goodbye as once you start, you won't be able to stop) with this free kindle edition, direct from Amazon (which makes it easier to read/sync than the *.mobi versions found around the Net).
If you like science fiction/space opera/hard space battle fiction, you'll very probably like this series.
