Series background & context

This is the series that put a lot of readers onto Karina Halle in the first place. It starts with Perry Palomino, a twenty something who sees ghosts, feels a little untethered in her own life, and keeps stumbling into things she probably should run from. Then she meets Dex Foray, an eccentric producer with a haunted look and a talent for dragging her into danger, and the whole thing kicks into gear.

Together they make a ghost hunting web series, but Experiment in Terror is not a neat case of the week setup. Each book does send Perry and Dex somewhere new, a lighthouse, a desert town, an island campground, mountain wilderness, New Orleans, a haunted school, but the real hook is what the investigations do to them. The supernatural threats are nasty, but the emotional fallout is often just as bad.

That is the core of the series. Perry and Dex are funny, stubborn, damaged, and drawn to each other long before either of them is ready to admit it. The books build that connection slowly, while also digging into Perry’s past, Dex’s secrets, and the cost of getting close to people who live around fear for a living.

The tone is a big part of the appeal. These books can be creepy, gross, tense, and genuinely scary, but they also have humor and a lot of heart. Perry’s voice keeps the series grounded even when things get wild, and Dex brings a mix of charm and chaos that keeps every scene a little off balance.

As the series goes on, the scope gets bigger. What starts as a rough, low budget webcast turns into something more dangerous and personal, and the mythology around the characters grows with it. There are bonus stories, side material, and spin off threads, but the center always comes back to Perry and Dex and the strange, messy partnership that keeps surviving the impossible.

If you like paranormal romance that actually leans into the paranormal, this is a good fit. It is road trip horror, slow burn romance, and emotional wreckage all at once.
