If you’d like to get a book reviewed for free you might want to have a look at Like a Free Review? This is an idea from a website called Book Tweeting Service which I have been looking into though haven’t used. You can also volunteer on there as a book reviewer which not only gets you some publicity but also is a networking opportunity.
Of course if you’d like me to review anything science fiction (and if I have time) then get in touch with me (contact details here). I can review on Amazon and may also get things onto StarBurst as well.
If you’ve used one of these services I’d like to know how it went. What others exist that you’d recommend?
