This is for all subgenres of sci-fi except erotica. No nekkid' man/alien/cyborg chests for this one. Short stories must be permafree. Boxsets are welcome. All mailing list sizes are fine, however only authors who send 50+ clicks per promo may have more than THREE ebooks. This is a great way to get eyes on books 1, 2, and 3 of your series!
