The Sins of the Zodiac Series in Order

About the Sins of the Zodiac series

Series Premise

In the fractured, war-torn continent known as the Waning Lands—divided into four elemental kingdoms of air, fire, earth, and water that are perpetually at war—the dragons have vanished, the elements rage unchecked, and conscription at age twenty-one is mandatory for all Fae to awaken their magic. Two young women from opposing sides are thrust into the brutal fortress of Never Keep, the only neutral ground where conscripts from the warring nations train and awaken their powers amid deadly trials, merciless Reapers, rampant werewolves, bloodthirsty vampire covens, and royal lies; as they uncover dangerous secrets the stars themselves hide, form forbidden alliances with enemies, and navigate treacherous hearts, they must survive awakening, betrayal, and a brewing war that could shatter the fragile peace.

The series must be read in order, as it unfolds a single, interconnected narrative with progressive character arcs, deepening mysteries about the continent's secrets and the missing dragons, escalating romantic and political tensions, and direct sequels that build on prior revelations, alliances, and emotional stakes—jumping ahead would spoil critical twists, identity reveals, and the slow-burn enemies-to-lovers progression that defines the saga.

Main Characters

The Dual Heroines: Two fierce, kick-ass female protagonists (often one from a lower-status background and another tied to power or royalty) who wield dark, corrupting magic (like hearts or corruption summoning); resilient, defiant, and unafraid to embrace their wickedness, they navigate awakening their powers, forming uneasy alliances, and falling into complicated entanglements while uncovering continent-shaking secrets.

- The Brooding Male Leads: Ruthless, sinful Fae men—enigmatic sinners and heathens from opposing kingdoms—who embody danger and desire; possessive, morally gray, and initially antagonistic, they challenge the heroines with hatred-fueled tension that ignites into obsessive passion, forcing both sides to confront vulnerability and redemption.

Setting

The stories center on the isolated, gothic fortress of Never Keep (and later locations like Echo Fort), a frigid, snow-swept castle perched in a desolate region that serves as the sole neutral training ground where conscripts from the four warring elemental kingdoms—air, fire, earth, and water—are forced together. This harsh, medieval-inspired world of the Waning Lands features elemental magic clashing violently, lost dragons, roaming supernatural threats (werewolves, vampires, Reapers), royal strongholds hiding corruption, and a broader continent scarred by perpetual war, with vivid contrasts between brutal training grounds, shadowed halls, forbidden wastelands, and the ever-present elemental chaos that fuels both destruction and awakening.

Tone & Themes

Dark, addictive, and scorchingly intense, the tone leans into raw passion, visceral danger, and unapologetic villainy with explicit steam, heart-pounding suspense, and a gritty edge that leaves hearts raw while delivering addictive page-turners. It balances brutal stakes with found-family warmth, sharp banter, and moments of vulnerability amid the chaos. Themes center on enemies-to-lovers redemption, the corrupting allure of power and forbidden desire, prejudice and division across elemental lines, uncovering hidden truths in a world built on lies, the cost of survival in endless war, fierce female empowerment, morally ambiguous choices, and the hope that even the most tainted souls can find light through connection and defiance.

The Sins of the Zodiac series scorches the page with its intoxicating blend of dark magic, forbidden enemies-to-lovers heat, and ruthless Fae who steal your heart while breaking it. Peckham and Valenti craft a villainous, pulse-racing spin-off that dives deeper into Solaria's shadows, where wicked souls clash, secrets unravel, and love emerges as the deadliest weapon—leaving readers breathless, obsessed, and utterly addicted to every sinful twist in this wickedly addictive romantasy realm.
