Summary
In the year 1709, as the War of Spanish Succession rages, Jamaica and England's other Caribbean colonies find themselves engulfed by the Spanish Empire, with few allies and precious little resources.
Scion of a powerful Pennsylvanian merchant family, Alexandria Woods is only in the running for a Navy captaincy because her father Augustus registered her as birth as 'his boy Alexander', and intends to prove herself by stamping out the scourge of piracy, or the Spanish - there is little difference in the Commander's eyes.
Countess Clarke Griffin is not your average noble lady, striking out from under her mother's oppressive thumb to seek her own fortune. Already a somewhat renowned physician at Utrecht University, the Bostonian noble wants to prove to herself that she doesn't need money or blue blood to be valuable, and a vacancy on a certain warship might just be the opportunity she's been waiting for.
Costia Greene is a Devonshire orphan with no title, no wealth, and no connections, posing as a man in an attempt to take her fate into her own hands and build a life worth having. The only problem is: whatever life she envisioned, she can no longer imagine without Lexa Woods and Clarke Griffin being a part of it.Series

Summary
Seven years after their last heartbreak, Senator Lexa Heda sees a news report that stops her in the middle of her morning routine. Clarke Griffin’s daughter is missing. The girl’s face is too familiar, too much like her own for Lexa to believe in coincidence. Desperate, Lexa casts a dangerous retrieval spell to bring the child to her… but something goes horribly wrong. Instead of finding the girl, the magic wipes everyone's memory of the missing child.
The community of Arkadia knows something is wrong, leaving Clarke to search for why people are avoiding her and the reason her heart is numb. Costia is on the run once more, terrified that she ruined everyone's life with her choices. And Lexa is waiting for her daughter in DC. But secrets in Arkadia run deep: Madi, the missing girl, is not who anyone thinks she is, and the real child at the center of this mystery is even closer than they realize.
In a tangle of lost memories, ghostly ties, and dangerous magic, three women will have to face the truth about love, family, and the price they paid for the walls they put up to protect each other.

Summary
In the ashes of war, peace feels fragile. Commander Lexa has secured unity for the Coalition, but her greatest strength has always been the one thing she cannot control: her heart. When Clarke returns to Polis, still torn between loyalty to her people and the love she cannot deny, she discovers a truth that shatters her—Costia, the woman Lexa once mourned, is alive. What follows is a story of impossible choices and devastating revelations. Lexa is forced to confront the love she lost, the love she’s found, and the deadly politics closing in on all sides. Clarke must decide whether she can trust Lexa again, even as their bond pulls them closer despite betrayal and pain. But danger does not wait for hearts to heal. Azgeda plots in the shadows, assassins lurk at every turn, and alliances fracture. As enemies circle and the Commander weakens beneath the weight of devotion, Clarke and Lexa must learn whether love is enough to endure the fire—or if it will be the very thing that destroys them. And yet, out of war and broken trust, a new future waits to be born: a child, Madi, they vow to protect, a promise of hope in a world built on ruin.

Summary
When Commander Lexa kom Trikru, ruler of the Thirteen Clans of the North American Earthers, is accidentally shot and killed by her Flamekeeper Titus, Azgeda’s Princess Ontari wastes no time in launching a coup in Polis and having herself declared the new Commander, despite not possessing the all-important Flame – the integrated circuit that now hosts Lexa’s consciousness. Said woman’s body is currently being taken to the Temple of the Order of the Flame by Clarke Griffin, de-facto leader of the Thirteenth Clan, Skaikru, the people from the conglomerate of space stations once known as The Ark that fell to Earth after its living conditions became untenable. Clarke and Lexa had only just consummated their burgeoning relationship when it was abruptly cut short, and Clarke is taking her lover’s body to be properly taken care of, only to come face to face with a ghost. Costia kom Trikru, Lexa’s first love, thought to have been captured and killed by the Ice Nation three years ago, is anything but dead, and she has returned to make good on a promise made long ago – and to enact a crazy plan to bring the dead Commander back to life.
