The Star Darlings have made a grave mistake: they wrongfully accused Lady Stella of causing the energy imbalance, and now the situation is worse than ever.
As they prepare for the Starshine Day celebration, all hope seems to hinge on Gemma, who is not so patiently waiting for the final Wish Orb, which will send her on her Wish Mission. Will she collect enough energy to reverse the energy crisis?
