Jisoo never meant to become a detective. She's the quiet one in her five-member K-pop girl group — the one who notices everything but rarely speaks up. But when their Christmas concert turns deadly and K-pop idol Soo-Ah is found murdered backstage, silence is no longer an option. Horrifying thought ... Could one of the band be a killer? Time to get sleuthing! With only her fluffy Shih Tzu, Pom Pom, for backup, Jisoo begins to untangle a web of secrets hidden beneath glittering stage lights and festive fanfare. From cryptic messages and vanishing accounts to perfume trails and forged contracts, every clue pulls her deeper into a mystery no one else seems willing to solve. As the snow falls over Edinburgh and the spotlight turns cold, Jisoo must find her voice — and the killer — before the curtain rises again. A diary-style, cosy, teen mystery with wit, heart, and a dash of glitter, perfect for K-pop fans.
