The fourth book in the Icelandic Romance series, set in Reykjavik Iceland. The series follows a group of friends.

Iris, an English volcanologist, arrives in Iceland focused solely on her research. But when she meets Siggi, a charismatic local with a complicated past, his passion for showing her Iceland's geological wonders ignites unexpected feelings.

Cautious but drawn to each other, they embark on a short-term romance, promising to part ways when Iris's work is done, but their deepening connection challenges the boundaries they've carefully set.

When a volatile volcano suddenly threatens everything, they're forced to confront not only the unstable landscape but also their own hearts. In a country where the ground can shift at any moment, can Iris and Siggi find a way to stand firm together?
