Five Frozen Hearts

You will hear five voices in this book. Once, these people were a family, but it was shattered in an instant — cruelly and irreversibly, like a house of cards.
Catherine and Mark were considered exemplary spouses and no less exemplary... parents. But, as often happens, not everything in their lives was serene and cloudless. For example, Catherine had long been disappointed in her marriage and found solace in the arms of a lover.
An ordinary affair, you might say. Yes, it was for a time exactly that. Until Catherine, the mother of the family, committed a terrible, irreparable act.
What was she thinking when she decided to do it? Well, certainly not about her family. Five people close to her — her mother, sister, husband, and two children — would henceforth survive alone, and no one would thaw their hearts.
