Republic

After the notorious outlaws Amaranthe and Sicarius helped overthrow the corrupt faction controlling the empire and brought in a great war hero to lead the nation to prosperity, they finally earned their pardons--and some time off. A tropical vacation cruising around in a private submarine? Perfect. But their trip is interrupted by a summons from the new president: they're needed back at home. Trouble unlike anything they've ever dealt with threatens to destroy the capital city and throw the fledgling republic into chaos.
The follow-up to The Emperor's Edge series, Republic takes place a few months after the events of Forged in Blood I & II. It is a complete 210,000-word novel.
