Some secrets drag you under...

Former ice diver Alyssa hasn't set foot in Lapilla since the night her best friend Tilda drowned beneath the ice. Officially, it was an accident - just like the one that killed Alyssa's father years earlier. But Alyssa has never believed in accidents.

Now, a family emergency forces her back to the frozen town she swore she'd never return to. Drawn once more to the dangerous pull of ice-diving, Alyssa begins digging into the mystery of Tilda's disappearance. While the locals are tight-lipped, it's clear the community that turned their backs on her friend is hiding something.

Then come the warnings: threatening messages, sabotaged gear. Someone doesn't want her asking questions. Someone wants her gone. As the anniversary of Tilda's disappearance looms, Alyssa must brave the unforgiving ice to uncover the truth. Before it claims her too.
