An action-packed fantasy series for middle grade fans of K-pop and the hottest animated movie of the decade! Moving into the trainee dorms brings new independence and new dangers. Hana and her friends begin seeing animal avatars: a gentle, watchful tiger and a mischievous little bird. At first, the bird seems harmless, but as the group prepares for their debut music video, its true nature as a shadow spirit emerges. To protect their music--their strongest weapon against the darkness--they must trust the tiger and their instincts.
