The Uprising of Persepolis. The Wrath of Tiamat

The old enemy returns. In a thousand star systems engulfed by humanity's expansion, new colonized worlds search for their path, balancing on the knife's edge between catastrophe and miracle. The aging warship "Rosinant" is fully occupied with maintaining a fragile... peace. The inner planets, along with the Belt, have created a tenuous and fragile alliance in the vast space between Earth and Jupiter, still haunted by the memories of past wars and prejudices. On the forgotten colonized world of Laconia, a lurking enemy envisions the future of humanity in their own way and holds the power to realize that vision. New technologies clash with the old in the eternal war for dominance. But within human nature, there is not only enmity; unleashed forces will demand their price. A price that will unexpectedly and forever change the face of humanity—and the "Rosinant".
One thousand three hundred gates have opened to solar systems throughout the galaxy. But as humanity builds its interstellar empire on the ruins of an alien civilization, mysteries and threats escalate. In the dead systems beyond the gates, where things more unusual than new planets lurk, Elvi Okoye desperately attempts to understand the nature of the genocide that occurred before the first human appeared, and seeks to find weapons for a war against almost unimaginable forces. But this knowledge may prove more expensive than she can afford to pay.
In the heart of the Laconian Empire, Teresa Duarte prepares to share the burden of power with her divinely-aspiring father. The palace is full of intrigues and dangers, and the sociopathic scientist Paolo Cortazar and the devilish prisoner James Holden are just two of them. But Teresa has her wits about her and secrets unknown even to the Emperor-Father. And across all the expanses of the human empire, the divided crew of the "Rosinant" is fighting rear-guard battles against the Duarte regime due to the circumstances. The old order is forgotten, and the future under the eternal rule of Laconia seems increasingly inevitable, bringing with it a war that humanity can only lose. For fighting against the lurking horror between worlds requires more than courage and ambition…
The collection also includes a new translation of the novella "Oberon".
