Tarthian Empire
Kayelle Allen · 6 series · 10 novels · 1 novella · 1 novelette · 3 short stories · 2005–2022
The Chosen do not die. They watch empires rise, take lovers who will not last, and carry the weight of every year they cannot shed. Around them turns the Tarthian Empire — a far-future sprawl of star systems, thieves' guilds, and imperial intrigue where Kayelle Allen threads space opera through the steady pulse of romance. One author, one cosmos, told across interlocking series. The Antonello Brothers follows Senth and Khyff, half-brothers bound to a thieves' guild and to each other; Antonello Brothers: Immortal carries that line forward. Tales of the Chosen turns to the ageless few who move unseen among mortals, while Gates of Life and Terran Crescent widen the map toward soldiers, colonists, and the not-quite-human made to serve them. Characters recur, debts are owed across books, and a rescue in one story echoes a lifetime away in another. The pleasures here are intimate more than cosmic: found family, slow-burn devotion, the particular ache of loving someone who will outlive you — or already has. Read for the people, not the physics. Newcomers do well to enter through the Antonello Brothers and follow the threads outward; the author keeps reading-order guides for anyone who wants the whole braided map.

4 works not in this orderThe Antonello Brothers saga (main line and its 'Immortal' continuation) is Kayelle Allen's most substantial thread in the Tarthian Empire, with the internal #0/#0.5 prequel ordinals honored ahead of the 2005 series opener. Tales of the Chosen, a separate three-book series with no confirmed link, is appended at the end rather than interleaved.
