While working the last two stories in the Knights and Necromancers series (stories five and six) I ran into this simple, yet complex, problem.
What does a matriarchy look like?
Or, more to the specific point I ran into with those two stories:
How would a woman from a matriarchy respond to visiting a patriarchy?
Knights and Necromancers three and four are ready to be released but you can get them a bit earlier than the rest.
The third and fourth book in the series have both been submitted to Kobo, Apple, and Amazon for their pre-publication vetting process (which, frankly, can take days).
But you can get them sooner, if you really really want. :-)
