In a world where everyone bears animal traits — ears, tails, instincts — and a rare bond can tie two people together for life, a new girl at Hawkins High finds herself caught between two boys who share something dangerous: a bond mark that burns hot and possessive. Eddie Munson, sharp-tongued and theatrical, wears his jealousy openly. Steve Harrington, quiet and intense, watches everything. When the bond flares between the three of them, it's instant, consuming, and feral. They don't just like her — they claim her. Anyone who looks too long, gets too close, or threatens her finds out fast: she's not available. Marked. Hunted. Kept. is a dark fantasy-style romance with yandere undertones, explicit content, and heavy themes of possession, protection, and obsessive love. Eddie and Steve are feral, clingy, and unapologetically jealous — and they'll burn the world before they let her go.
