Winter Break turns deadly when Rory Quinn and her treasure-hunter grandmother travel to Iceland in search of an enchanted artifact.

Their mission is to recover a blood-smeared stone that legend says will lead whoever possesses it to the nearest doorway to Hell. The client’s grandson, Einar, took the stone at the request of his favorite heavy metal band. As part of a publicity stunt, the band plans to open the closest doorway, rumored to exist deep inside one of Iceland’s many volcanoes, in just three days.

Along with Einar’s twin brother, Gunnar, Rory and Gram will need to navigate glaciers, ice caves, and volcanic tunnels in search of the missing artifact. But can the three of them recover the stone before the band unleashes anything evil into the Icelandic wilderness?

As the team grows closer to Einar, Rory is growing closer to Gunnar, too. But she can tell he’s keeping secrets from her. Big ones, that when revealed, will cause her to question almost everything she’s ever believed.
