As the city that produces the most selium – that precious gas that elevates airships and powers strange magic – Hond Steading is a jewel worth stealing. To shore up the city’s defenses, Detan promises his aunt that he’ll recover Nouli, the infamous engineer who built the century gates that protect the imperial capital of Valathea. But Nouli is imprisoned on the Remnant Isles, an impervious island prison run by the empire, and it’s Detan’s fault. Detan doesn’t dare approach Nouli himself, so his companions volunteer to get themselves locked up to make contact with Nouli and convince him to help. Now Detan has to break them all out of prison, and he’s going to need the help of a half-mad doppel to do it.

After Detan retrieves the renowned engineer Nouli from the clutches of the empire, he returns to his aunt’s city to find it under siege by Thratia’s army. With Nouli’s help, they turn back the tide – -until imperial forces show up, prepared to hammer Thratia’s army against the anvil of the city’s walls. Worse yet, the imperial advance is aided by an elite force of deviant magic users. His aunt is forced to forge an uneasy alliance with Thratia to keep the city from falling back under imperial control – but Detan’s wary.

After rescuing the renowned engineer Nouli from the clutches of the empire, the valiant rogue has returned to his aunt’s city – to find it under siege by Thratia’s army. With Nouli’s help, they manage to turn back the tide, at least until imperial forces descend, prepared to hammer the Thratian force against the anvil of the city’s walls. Worse yet, the imperial advance is aided by an elite force of dark magicians.His aunt is forced to forge an uneasy alliance with Thratia to keep the city from falling back under imperial control – but Detan’s wary. While Thratia and his aunt bring their forces to bear against the new threat, Detan puts his own plans into motion – to ensure that when the final blow is dealt, Thratia and her army will find themselves on the other side of the city’s walls.

Detan Honding, a wanted conman of noble birth and ignoble tongue, has found himself in the oasis city of Aransa. He and his trusted companion Tibs may have pulled off one too many cons against the city’s elite and need to make a quick escape. They set their sights on their biggest heist yet – the gorgeous airship of the exiled commodore Thratia. But in the middle of his scheme, a face changer known as a doppel starts murdering key members of Aransa’s government. The sudden paranoia makes Detan’s plans of stealing Thratia’s ship that much harder. And with this sudden power vacuum, Thratia can solidify her power and wreak havoc against the Empire. But the doppel isn’t working for Thratia and has her own intentions. Did Detan accidentally walk into a revolution and a crusade? He has to be careful – there’s a reason most people think he’s dead. And if his dangerous secret gets revealed, he has a lot more to worry about than a stolen airship.

Stranded on a dead planet with her mortal enemy, a spy must survive and uncover a conspiracy in the first book of an epic space opera trilogy by an award‑winning author.

She’s a revolutionary. Humanity is running out of options. Habitable planets are being destroyed as quickly as they’re found and Naira Sharp thinks she knows the reason why. The all-powerful Mercator family has been controlling the exploration of the universe for decades, and exploiting any materials they find along the way under the guise of helping humanity’s expansion. But Naira knows the truth, and she plans to bring the whole family down from the inside.

He’s the heir to the dynasty. Tarquin Mercator never wanted to run a galaxy-spanning business empire. He just wanted to study rocks and read books. But Tarquin’s father has tasked him with monitoring the settlement of a new planet, and he doesn’t really have a choice in the matter. 

Disguised as Tarquin’s new bodyguard, Naira plans to destroy the settlement ship before they make land. But neither of them expects to end up stranded on a dead planet. To survive and keep her secret, Naira will have to join forces with the man she’s sworn to hate. And together they will uncover a plot that’s bigger than both of them.
