Dragon's Echo - The Dragon Corps, #6

Book 6 in the DRAGON CORPS series by Natalie Grey, author of SHADOWS OF MAGIC and the TRIALS & TRIBULATIONS and VIGILANTE series in the Kurtherian Gambit Universe! New to the series? Start with DRAGON'S COVENANT! Promoted, Nyx is now in command of the Conway, bringing her old crew on the Ariane with her. She already has a first mission in mind: take out the last of the renegade Dragons. Nyx and Talon have always been an unstoppable team.
Now that they both have their own crews, they're even more lethal. There may be one huge hitch in that plan though. Though Nyx took down Ghost, the AI modeled on the smuggler lives on, now sentient and running what remains of the organization. When one of Ghost's assassins attacks the Conway, Nyx is determined not to let it derail her mission. She's going to help Talon and the Ariane no matter what it takes. But Ghost doesn't just want Nyx dead, she wants Nyx destroyed.
And her assassin knows that the best way to break Nyx's spirit is to force her to choose who survives.. The crew of the Ariane, or the crew of the Conway.
