Re(4): On getting our books reviewed Posted on 7/29/2015 at 07:43:01 PM by Peter DiChellis
For short science fiction readers, you might try the website SFRevu. Here are links to the homepage and the contact page for the short fiction reviewer. (Or Google: sfrevu)
I'm aware of this site because the editor also runs a mystery fiction review site. Doubt you'll get anywhere near the exposure as with the Big Three, but what the heck.
