   Summary

   On an ordinary winter day, Sirius found his younger brother collapsed in the snow outside his door. Faced with his brother's injuries, Sirius swore to find out the truth. This is a story of love and redemption. Sirius and Regulus must confront their inner selves. In the process of exploration and healing, the feelings they've buried deep within can no longer be contained.

   Or

   A fluffy story about healing trauma, and a piece of smut filled with the author's depraved fantasies.
