In this day and age, it's no surprise that the Internet has many outlets for finding your next great read. The trick is in finding the good ones. If you like speculative fiction – that is, science fiction, fantasy, and horror – I've got good news. I've rounded up some of the best destinations for finding your next great read online. The best part: all of them offer stories that are absolutely free.

However, rather than adopt a "read and run" strategy, might I recommend an approach that will reward you as a reader again and again? Keep coming back to these venues. Consider them ongoing sources for terrific fiction, not just for their archives, but also for the new stuff they continue to publish. You get the benefit of being introduced to new authors and expanding your reading horizons…which leads to many more existing stories for you to enjoy.  And hey, most of these outlets are magazines which also offer eBook subscriptions, so do consider supporting them so that they can keep delivering the goods.
