Lost in Yellowstone: A National Park Mystery

National Park Mysteries #2

by Nicole Maggi

A foot in a geyser. A school in the wild. A truth no one saw coming.

When a human foot is ejected from a geyser in Yellowstone National Park, Special Agent Emme Helliwell of the National Park Service is assigned the chilling case.


Tasked with identifying the victim and uncovering what led to such a grisly end, Emme is drawn into the park's vast, unforgiving wilderness—and into the orbit of a private school for at-risk teens where extreme backcountry excursions are part of the curriculum. As disturbing truths begin to surface, Emme must also confront personal fault lines, including the unresolved tension with an ex-boyfriend who's suddenly back in her life and assigned to the same case.


In a place where danger hides behind natural beauty and good intentions can mask darker motives, Emme must navigate both treacherous terrain and emotional landmines to solve a mystery that could cost her everything.

Perfect for readers of C. J. Box and Lisa Gardner

About the author

Nicole was born in the suburban farm country of upstate New York, and began writing at a very early age. Of course, her early works consisted mainly of poems about rainbows and unicorns, although one of them was good enough to win honorable mention in a national poetry contest! (Perhaps one of the judges was a ten-year-old girl.) Throughout high school, her creative writing was always nurtured and encouraged.

Nicole attended Emerson College as an acting major, and graduated cum laude with a Bachelor of Fine Arts degree. Post-college, she worked as an actress in New York City for over a decade, focusing mainly on Shakespeare and the classics.

Now living in Los Angeles, Nicole balances writing full-time with motherhood. WINTER FALLS, the first in her TWIN WILLOWS TRILOGY (Medallion Press, 2014) is her debut novel. She has a stand-alone novel, HEARTLINES, coming out in February 2015 with SourceBooks Fire, as well as the second and third novels in the TWIN WILLOWS TRILOGY in 2015 and 2016.

I enjoyed this mystery set in the beauty of Yellowstone. The imagery was gorgeous and you really feel the vibe of the parks. The ending was pretty predictable, but it was still enjoyable!
