Author looking for honest reviews
If you like to read and are interested in getting free "Advance Review Copies" (ARCs) of new books, usually before they are released, you should check out Netgalley. Basically, the idea is that publishers and authors will give you a free digital copy of their new books, and you consider writing an honest review. Writing a review isn't strictly required, though you need to review some percentage of the free books you claim (80% I think) in order to maintain good standing on the platform.
I'm currently looking for ARC readers for my first scifi novel, which I think (hope?) falls into the "hard scifi" genre. I studied computer science, linguistics, and philosophy at Stanford before working on DARPA-funded research in A.I. and then later in private enterprise. I've also presented papers at academic conferences on topics in A.I., Virtual Reality, and Ethics. Those are the general subjects of the book: In the Shadow of Humanity.
The book is brand new, and if you're interested in getting a free copy and are willing to consider writing an honest review, you can find it on Netgalley here. It's also free from Amazon at the link above if you have Kindle Unlimited.
I wrote the book for some of the same reasons you all joined this sub: I like my speculation to be grounded in reality, and I like to take "what if" questions seriously. More than anything, if you read the book and would like to discuss the topics it treats, please reach out to me!
Note: This is not the literary equivalent of a scifi action flick. My handle is u/scifirealism because my goal is to write serious science fiction blended with elements of realism. "Asimov meets Dostoevsky (but with only 5% of their talent)" is what I aspire to when writing. Personally, I think literary realism combines very nicely with hard scifi--but it's not for everyone.
