Long Biography (150 Words)
Tessa Barbosa loved books so much that after too many late nights awake reading and eating distractedly at the table, her parents banned her from reading. It didn’t work. Tessa stuffed books under her mattress, hid them in her sweaters, and many poor paperbacks met their ruin in a hot bath.
Tessa majored in computer science, and minored in the fine arts. After graduation, she switched from a career in software development to technical writing, because words were always her first love. Now she writes software help by day, and fantasy novels by night. She is the author of ISLE OF TEETH (S&S 2026) and THE MOONLIGHT BLADE (Entangled 2023).

Lady Death always comes to collect.
Matiu Frankel joined the imperial military to escape his childhood: his father’s wretched creations, his witch-mother’s loyalty to Lady Death, and the haunting voice in his own head. With no choice in assignment, however, he returns home to Song—and to a waiting nightmare. A revenant attack waylays his mission and Matiu, being part-Songi, is accused of working with native insurgents. To remove the bounty on his head, Matiu must prove his loyalty to the Lyssian Empire by infiltrating the resistance and capturing the monster they’ve weaponized.
But Calyx is not a monster. A revenant pieced together from animals and dead Songi, yes. Abandoned by her makers to rot on the Isle of Teeth, yes. But not a monster. At least, not yet. Without medicine, Calyx and her siblings risk losing their humanity to Lady Death’s whispers.
Calyx has three weeks to find a cure. Matiu has even less time to clear his name. In their desperation to survive, they turn to each other, becoming entangled in each other’s stories—and in the larger story of empire and resistance. Amidst growing tensions and the echoing calls of the goddess of death, Matiu and Calyx’s relationship transforms into a dark fable about those who have spent their lives with a boot on their neck—and what they would sacrifice to stand tall once more.

I promised my mother I would never come to Bato-Ko…and yet here I am.
Narra Jal is one of the cursed, cast aside her whole life, considered unlucky. But with her mother’s life on the line, she will return to the city where she was born to face the trials: a grueling, bloodthirsty series of challenges designed to weed out the weak, the greedy, and the foolish. Trials to select the next ruler of Tigang.
Narra has nothing. No weapons. No training. No magic. No real chance of leaving with her life. Just her fierce grit and a refusal to accept the destiny she’s been handed. Even the intense, dark-eyed Guardian she feels a strangely electric connection with cannot help her. Narra is on her own. But she’ll show everyone what the unlucky can do.
Let the bloodbath begin.
