Everyone loves receiving mail, unless it's deadly.

Ella’s world turns upside down when the Postmaster is found dead on her doorstep—holding a letter addressed to her.

Someone in Gloamington is using the mail to murder, and Ella Bloom might be next.

With her true identity finally revealed, Ella has become a target. Her presence in Gloamington puts everyone she loves in danger. Now a killer is on the loose, and Ella and Malcolm must discover who sent the lethal message before they strike again.

But as they hunt for a murderer who knows how to weaponize the mail, they face an impossible question: Is the killer the enemy Ella fears most, or someone hiding in plain sight?

Can Ella and Malcolm unmask a magical murderer before the next delivery arrives? Or will discovering who really sent that package cost Ella everything—including the town she's sworn to protect?
