Galactic Thunder

Danny and her crew learn that humans may not be alone in the galaxy. 

 
Thirty years ago, Danny and her crew on the Supreme Lythion were instrumental in the defeat of the sentient array, the crumbling of the Empire and the development of crescent ships. 
 
Now wildcat crescent ships are opening up the known galaxy, finding more worlds to be settled and new resources.  When the wildcat ship Ige Ibas goes dark and silent, Dalton comes to Danny for help, because his son, Mace, is on that ship. Despite their history, Danny agrees to try to find Mace. 
 
But the Ige Ibas has gone dark for a reason, and Danny’s investigation rouses the ire of a new enemy, one that emerges from beyond any worlds known to humans…
