Blood on the Trailhead follows the Chief of Police for a state park who is investigating several cases involving a mutilated body, strange glyphs, and a missing child, all leading to a supernatural cause. What was the inspiration for the setup of your story?

Our inspiration all started around the Indigenous myth of the Tah-tah-kle’-ah. Feel free to Google it, but be warned, it will be a big spoiler. Therefore, we don’t want to elaborate here, knowing many people have not read the book yet.

We were also very inspired by the beauty and the vastness (Redwoods) surrounding Ferndale, CA, which is the town that we modeled the small city of Lost Grove after. There is still so much wilderness that holds pockets of secrets that we have yet to uncover. We found this fertile ground to explore in this story.

What were some ideas that were important for you to personify in your characters?

A big one for this book was nature conservation and the preservation of cultures, specifically the Wiyot tribe of Northern CA. Both of these are throughlines that run through the horror and mystery in the story. One of the other ideas we cling to in the Lost Grove series is the close-knit mentality of the small town of just under 1,500 residents, their resilience, and camaraderie. We see this among the teens and in the small police force. Lastly, and this is more so a focus for Alex, is always keeping a sense of humor in the characters that feels grounded and true to who they are. 

What intrigues you about the horror and paranormal genres that led you to write this book?

Well, we both absolutely love horror in any fictional medium. We watch over one hundred horror films a year and host our own year-end Horror Oscars. We also love the depth that horror offers its lead characters, placing them in life-or-death situations that reveal everything about a person. The draw to paranormal is the intrigue of the unexplained that exists and persists in our world. The paranormal also gives us a chance to explore things beyond what we experience in most of our day-to-day lives. Charlotte, in particular, has always been fond of folklore and superstition, which are ripe to explore in this sub-genre. 

What is the next book that you are working on, and when can your fans expect it to be out?

Regarding Lost Grove, they can expect book four next fall. The working title is The Devil’s Acre, and it will return readers to Lost Grove during one of its darkest winters. Cold Cases, isolation…it may be one of the more unsettling books in the series so far.

Charlotte is also wrapping up an epic fantasy trilogy, Trust of the Magdrid that she has been working on for some time now. She hopes to release the first in that series late next year as well.

Alex is in the midst of his own mystery trilogy. Book one, The Disappearance at Devil’s Churn, is complete. He is planning to begin work on book two at the start of 2026. He is waiting until he finishes book three before releasing any of the books, as they will be released in quick succession.
