Awesome!! My top picks are:
Elizabeth Moon's Deed of Paksenarrion (fantasy), my favorite book ever. The first book in the trilogy,
Sheepfarmer's Daughter, is in the free library.
David Weber's Honor Harrington series (military sci fi), the first two are in the free library.
On Basilisk Station
Sharon Lee & Steve Miller's
Liaden Universe books (space opera? not sure how to categorize them). None of them are free, but IMHO they're worth at least twice what the various books cost at Baen. I started with Conflict of Honors, but Local Custom is first chronologically in the regular series, or you could start with the Crystal Soldier & Crystal Dragon prequels. More info on the series is
here.
