In the city of Marrow, every life is bound threads visible to few. These threads represent connections to others: vibrant gold for love, silver for friendship, crimson for betrayal, and black for death. Once severed, a thread can never be repaired.
Seventeen-year-old Lira Solace has always seen the threads of others, a rare and cursed ability that forces her to witness bonds breaking, mending, or fading altogether. When her own golden thread to her boyfriend, Elias, vanishes without warning, Lira's life is upended. She is thrust into the underbelly of Marrow, a dangerous world ruled by the enigmatic Weaver's Guild, the shadowy organization responsible for the threads.
Desperate to uncover the truth behind Elias's disappearance, Lira teams up with Cade, a rogue guild apprentice with secrets of his own. Together, they uncover a chilling truth: someone is deliberately severing threads, unraveling the fabric of relationships across the city, and leaving its victims empty shells of their former selves.
As Lira digs deeper, she learns her own thread may hold a secret that could destroy the Guild-or save it. But the closer she gets to the truth, the more tangled her own fate becomes, and Lira must decide what she's willing to risk to mend the threads that bind her to Elias-and to herself.
