Hallowmere University thrives on rivalry, reputation, and chaos. Elite athletes rule campus social hierarchies while old-money families, dangerous secrets, and violent team rivalries simmer beneath gothic architecture and centuries-old traditions. Most students never notice the monsters hiding among them. Guest is one of those monsters. Attempting to blend into ordinary university life while hiding their supernatural nature, Guest catches the attention of Hallowmere's emotionally unstable hockey captain almost immediately. Nikolai Vukovic never learned how to care halfway. Loud, reckless, fiercely loyal, and dangerously possessive once attached, Nikolai quickly becomes consumed by Guest in ways neither of them fully understand. As campus drama escalates, the Harrows close ranks, rival teams circle like sharks, and secrets become increasingly difficult to keep. The problem? Guest is trying very hard to remain hidden. Nikolai has already started planning forever.
