Xmas Break

Isla and her sister Clara have not spoken since their mother died. When Clara invites her to spend Christmas at a luxury mountain retreat, Isla accepts, expecting an awkward few days and some overdue conversation.

A snowstorm cuts the retreat off from everything. In the days that follow, the reasons for the silence between them start coming out, along with a good deal that neither sister knew.

J.E. Rowney structures it in twenty-five chapters, one per day of advent, and by the point the weather closes in the question is less about reconciliation than about which of the people in the house is telling the truth.
