Piper, Ghost Hunter is a brilliant but clumsy ghost hunter who created a device that makes the invisible visible. With her perpetually sliding glasses and tendency to trip over her own equipment, she might not seem like your typical paranormal investigator, but her knowledge of spectral phenomena is unmatched. Her loyal companion is Scout, the ghostly form of her childhood dog who became her first successful spirit manifestation.

Driven by the loss of a parent at a young age, Piper has dedicated her life to perfecting her ghost-manifesting technology. Her ultimate goal is to find her parent's spirit and finally say the goodbye she never got. However, her invention has an unexpected side effect – it not only reveals ghosts but gives them increased influence over the physical world, creating both opportunities and dangers.

Now Piper needs Avery's help investigating hauntings and managing unexpected spectral encounters while she searches for her parent's spirit. Despite her nervous nature and tendency to hide behind Avery when things get scary, her determination always wins out in the end.

Piper's invention, the Spectral Amplifier, is as unpredictable as it is revolutionary. In minimally haunted areas, it creates a small bubble where ghosts can manifest, but in truly haunted locations, it can activate an entire building's worth of spirits. The device has one significant drawback - once activated, it can't be shut down until either the sun rises or the spirits' unfinished business is resolved. This makes every investigation a race against time, especially when the Amplifier malfunctions in particularly haunted locations, requiring Piper to make repairs while surrounded by increasingly powerful manifestations.
