"If she dies, I'll die," are the words 15-year-old Mia Perlman writes in her journal the night her mother is diagnosed with cancer. Twelve days later, Mia's mother is dead, and Mia, her older sister, and their father must find a way to live on in the face of sudden, unfathomable loss.

For Mia, this means getting through a funeral led by a rabbi who belongs in Las Vegas; dealing with a social worker who appears to have been educated at the local beauty academy; sharing "healthy heart" meals with her father, who seems to be seeing her for the first time; trying to relate to her sister, whose idea of fun is solving quadtratic equations; and developing a crush on Cancer Guy, who is actually kind of cute. But mostly it means carrying the image of her mother with her everywhere, because some kinds of love never die. Still, even in grief there is the chance for new beginnings.
