Ava Dellaira's debut novel, Love Letters to the Dead tugs at our heart strings at all the right moments, as we read Laurel’s thoughts about her sister’s sudden death, and experience her struggle to find out who she is without her sister’s very big, and loving presence. It’s novel of loss, but it’s also a novel of secrets, the kind that need to be shared, so Laurel can move on.

  Delia and Nora Ephron were writing partners; they co-wrote the movies You've Got Mail and The Sisterhood of the Traveling Pants as well as the off-Broadway hit Love, Loss and What I Wore. Delia was an assistant producer on Nora's film Sleepless in Seattle.

In her latest book, Sister Mother Husband Dog, novelist Delia Ephron writes that losing her older sister, Nora Ephron, was like "losing an arm, it's that deranging." Nora, who wrote When Harry Met Sally, died of acute myeloid leukemia in June 2012.

But for all their collaboration and closeness, Delia acknowledges that sister relationships are complicated. Sister Mother Husband Dog is a collection of autobiographical essays.

    Lyrysa Smith’s sister, Molly, got a severe brain injury from carbon monoxide poisoning. Her husband died lying next to her in the hotel bed. After nine days in a coma, Molly emerged. But not the Molly that Lyrysa knew.

Her new book, A Normal Life: A Sister’s Odyssey Through Brain Injury, is not a story about recovery. Molly got better, then worse, and then simply different.

Lyrysa tells the story of her sister’s brain injury—its impact on her, their close relationship, and their entire family. She looks to how they were all turned inside out and forever changed by the harrowing complexities of this most damaging and mysterious of injuries.

No matter where she went, she could not escape the image of her twin.
