The sexy female alien warrior shown on the cover of Book 15 is named Calenza Baxtion; she is an aquatic being, a Newteron, from planet Macur. You'll have to read the book to find out if she's a good guy or a bad guy...
Plus I did a promo over on Twitter called #WhoIsOctaviaMagnus? And it was also tied to Book 15.
Some fans think that Octavia is shown on the cover of the new book, but clearly that is not the case [even though Octavia and Calenza are both female aliens with light-blue skin tones]. Yet Calenza is a Newteron with a tail, while Octavia is a Nauticon; and there's a big difference between them, in terms of their powers and their personalities...
Based in an alternate galaxy, the DSNG Chronicles are centered around the main protagonist Prince Azzar [an alpha Senturi super-soldier] and his associates, who hail from planet Avera. And those that are joining this Mature Sci Fi Saga for the first time can still catch up on the story, as you read the latest tale!
