A mother and her son vanish into the wilderness. Time is running out.

When a woman and her neurodiverse teenage son go missing in the rugged parklands outside Honolulu, homicide detective Kimo Kanapa’aka is called in to lead the search. Every hour matters. The terrain is unforgiving. The trail is unclear. And the longer they’re missing, the slimmer the chances of finding them alive.

As Kimo and his team push deeper into the mountains, the case grows more complicated. Conflicting accounts, hidden tensions, and unexpected connections suggest this is more than a simple disappearance.

Someone knows what happened. And they’re not talking.

With media scrutiny intensifying and pressure mounting from officials desperate to protect the island’s image, Kimo must navigate both the physical dangers of the search—and the human ones lurking beneath the surface.

At home, the case hits close to the heart, forcing Kimo and Mike Riccardi to confront difficult questions about what it means to protect the people you love… and when you have to let them find their own way.

Because in the wild, survival isn’t guaranteed. And not everyone who goes missing is meant to be found.

The heart and warmth of Kimo’s ohana will provide the answers in this thrilling new mystery from an award-winning author.
