White Out - Susan Kiernan-Lewis

Sarah faces the world her children will inherit but one no mother should ever live to see. As life in post-apocalyptic Ireland teeters on the brink of the abyss, she's forced to rise up to do what needs doing--alone and against all odds.

In spite of Mike's resistance and David's deadly ultimatum, Sarah will need to do the unthinkable one last time to finally bring her family home.

Once and for all.
