The best-selling, beloved writer of romantic comedies like You've Got Mail tells her own late-in-life love story, complete with a tragic second act and joyous resolution.

Delia Ephron had struggled through several years of heartbreak. She'd lost her sister, Nora, and then her husband, Jerry, both to cancer. Several months after Jerry's death, she decided to make one small change in her life - she shut down his landline, which crashed her internet. She ended up in Verizon hell.

She channeled her grief the best way she knew: by writing a New York Times op-ed. The piece caught the attention of Peter, a Bay Area psychiatrist, who emailed her to commiserate. Recently widowed himself, he reminded her that they had shared a few dates 54 years before, set up by Nora. Delia did not remember him, but after several weeks of exchanging emails and '60s folk songs, he flew east to see her. They were crazy, utterly, in love.

But this was not a rom-com: Four months later, she was diagnosed with AML, a fierce leukemia.

In Left on Tenth, Delia Ephron enchants as she seesaws us between tears and laughter, navigating the suicidal lows of enduring cutting-edge treatment and the giddy highs of a second chance at love. With Peter and her close girlfriends by her side, with startling clarity, warmth, and honesty about facing death, Ephron invites us to join her team of warriors and become believers ourselves.
