Sins of the Zodiac (Susanne Valenti) Books in Order

Sins of the Zodiac returns to the Solaria universe, but it comes in with a different mood from Zodiac Academy. The official pitch is clear about that. This is a darker, more villainous story, one that wants the romance to feel dangerous and the cast to be harder to trust.

The wider world is already in bad shape when the series begins. The dragons are lost. The elements are at war. Power is concentrated in frightening places, and the people caught in the middle do not have much room for clean heroism. That atmosphere shapes everything.

This is Solaria with fewer safety rails.

At the center are characters pulled from enemy sides of that broken world, including the outcast Everest Arcadia and the feared Vesper. Their paths run through Never Keep and the Reapers, which gives the series a strong academy or fortress energy, but it never feels like a simple repeat of Zodiac Academy. The conflicts are harsher, the mistrust is deeper, and the emotional tone is more openly feral.

Because this is part of the same universe, long-time readers will catch echoes and connections. But the series is not built as homework. It is meant to stand as its own romantasy line, with a new cast, a new central conflict, and a stronger taste for characters who might be one bad decision away from disaster.

If what you liked most about Solaria was the shared world, the elemental magic, and the feeling that love and danger are always arriving together, Sins of the Zodiac keeps that. It just filters it through a nastier lens. That makes it a good fit for readers who want the spin-off to feel familiar in setting but sharper in tone.
