I'm posting this a couple of days ahead of time, so those (like me) who get the digest may be able to take advantage of it. My SF novel Twin-Bred's last free days on Amazon, at least for the foreseeable future, are coming up this Tuesday and Wednesday, May 8th and 9th. (I'm leaving the KDP Select program on May 10th.) Twin-Bred won't be free again until just before the sequel comes out, sometime this fall (I hope).
