While technically not a Hugo Award, I encourage every Hugo voter to nominate for the Campbell Award for best new author. A great many excellent writers have joined the science fiction and fantasy field in the past two years. You can see a list of many of them over at the Writertopia Campbell page.
Here in alphabetical order are the new authors I am planning to nominate. Yes, I am crass enough to nominate myself, not because I think I have any chance of making the ballot, but because even seeing myself on the list of nominated authors would be a thrill. For each author, I'm listing one or two works to start with, if you're interested in giving these authors a try:
Monica Byrne ("Nine Bodies of Water," Fantasy; "Five Letters from New Laverne," Shimmer)
Van Aaron Hughes ("The Dualist," Writers of the Future Vol. 27; "Random Fire," Abyss & Apex)
Stina Leicht (Of Blood and Honey; And Blue Skies from Pain)
Patrick O'Sullivan ("Maddy Dune's First and Only Spelling Bee," Writers of the Future Vol. 27)
Brad R. Torgersen ("Ray of Light," Analog; "Exanastasis," Writers of the Future Vol. 26)
Monica Byrne and Brad Torgersen are in their second year of eligibility, while the others will get another chance next year. From this list, I think Stina Leicht and Brad Torgersen are the most likely to make the ballot. Nominations are due March 11.
Good luck to all the eligible new writers!
