An Aggregation for Your Reading Pleasure

We owe

Patrick Abbott

our gratitude for putting this list together. And he’s got some fiction of his own available. I encourage you to check it out and see if it’s up your alley.

Substack Science Fiction and Fantasy Index

As part of my support for independent creators, I am planning a series of indexes to increase discoverability on Substack. This list is a collection of science fiction and fantasy Substacks. Check them out for new, original stories. Note: This list isn’t an endorsement, but an index to help readers. Nominators provided their own titles and descriptions. I edited for formatting and standardized spellings.

For the next index, I am looking for Substackers who do book reviews. Please let me know if you know some!
