For the second year in a row, I have done a simple analysis of the Goodreads’s Choice Awards for science fiction novels. Members of the Goodreads website vote on the awards. Fifteen books were nominated based on their review ratings on Amazon, and five more were nominated by readers. The concept part of my analysis is an interpretation of the novel’s Goodreads blurb, which led me, correctly or not, to allocate the novel a sub-genre (Note: I have changed some of the sub-genre categories since the initial post).

Concept. 

The First Fifteen Lives of Harry August sounds refreshingly interesting: Harry August and some others are born, live their lives, die, and then are reborn in the exact same fashion, in the exact same time and place, as their first birth, but with all their memories intact. Sand also sounds interesting. But a lot of the novel concepts sound very familiar. 

Sub-genre.

Some of the novels fit into several sub-genres, like The Long Mars, which appears to be a dystopian-space-opera-thriller. So, if you add up the following stats, they will come to way over 20. The novels appear to fit into the following sub-genres:

Thriller 12
Dystopian 4
Space opera 4
Alien invasion 3
Time-travel 3
Post-apocalyptic 2
Military 2
Mystery 1
Romance 1
Adventure 1

So thrillers are the predominant sub-genre in the Goodreads Choice Awards, with a few dystopian, space opera, post-apocalyptic and time travel novels.

In the 2013 awards I had the following sub-genres:

Dystopian 6
First-contact 5
Military 2
Space opera 2
Thriller 2
Military/first contact 1
Dystopian/military 1
Techno-Thriller 1

There seemed to be a lot more thrillers in 2014, a year when first-contact novels fell out of favour. Dystopian novels had a strong presence in both years.

Series.

Thirteen of the novels were parts of series. Four of those were the first in a series. One (Sand) was an omnibus of five novellas, so only six were standalone novels. This is almost the same as 2013 where 13 novels were also part of a series, five of which were the first book in a series, leaving only seven as standalone novels. 

Debut Novel.

As in 2013, there are only three debut novelists, which makes sense considering eight of the novels were sequels. 

Nationality of Authors.

A couple of the books had two authors. Overwhelmingly the authors were American. The exceptions were three British and one Canadian. The nationalities of the authors was more widely spread in 2013 with 16 Americans, four British, one Australian, one Barbadian and one Canadian. 

Nominated In Both Years.

Twelve authors had novels on both the 2013 and 2014 Goodreads Choice Awards lists. They were Hugh Howey, Orson Scott Card and Aaron Johnston, John Scalzi, Ben H. Winters, Daniel Abraham and Ty Franck, Terry Prachett and Stephen Baxter, Marko Kloos, Marcus Sakey, and Anne Leckie. Seven of the books in the 2014 list were sequels to novels in the 2013 list.

How to Write a Favourite Science Fiction Book.

Ideally you will be an already published American author who writes a dystopian/post apocalyptic-thriller series with aliens and time-travelling spaceships in it.
