All of which made me think there should be, there must be, at least one book with Marinaâ??s name on the spine. Publishers arenâ??t eager to take chances these days, but I hoped that one would have the guts, the heart, to make a slim, posthumous collection of Marinaâ??s stories and essays and poems. I could actually see the book in my mind, stacked on the front table of a sunlit bookstore, perhaps the Yale bookstore, where Iâ??m sure Marina dreamed about her work appearing one day.

A year later, it came in the mail, the very book Iâ??d seen in my mind, with the only possible title: The Opposite of Loneliness. I studied the striking cover photo and felt a wave of sorrow and joy. Then I sat down and read it and that sorrow-joy feeling became my constant companion over the next several days.

This is a book full of wonders. This is a book full of sentences that any writer, 21 or 101, would be proud to have authored. This is a book that will speak to young readers, because it expresses some of that inexpressible anxiety of starting out, of making life's first momentous choices, of wanting and fearing and needing and hoping and dreading everything at the same time. It will also speak to older readers, because itâ??s an inspiring reminder of youthâ??s brimming energy, its quivering sense of possibility.

Young people get a bad rap for thinking theyâ??re immortal, and acting accordingly, but Marina dwelled on the end. Hers, civilizationâ??s, the sunâ??s. â??And time, that takes survey of all the world, must have a stop.â?? She must have heard her beloved adviser Harold Bloom expound many times on Hotspurâ??s line, and clearly she took it to heart, personalized it. Savor every half-second, she seemed to be saying, to herself, to her readers, and her meditations on death, once charmingly precocious, now feel breathtakingly premonitory. Describing a group of fifty whales beached near her house on Cape Cod, she laments that their songs donâ??t transmit on land, and thus they canâ??t communicate their final thoughts. â??I imagined dying slowly next to my mother or a lover, helplessly unable to relay my parting message.â??

Such was her fate. And yet it wasn't, not really. This book is her parting message, exquisitely relayed.

And itâ??s not a mournful message. Thereâ??s so much light and humor here. In the title essay alone I hear glimmers of Lorrie Moore, Ann Beattie, Fran Lebowitz. For example, when Marina worries that other kids are sprinting ahead of her, embarking on fabulous careers while sheâ??s still clinging to the cocoon of Yale. â??Some of us have focused ourselves. Some of us know exactly what we want and are on the path to get it; already going to med school, working at the perfect NGO, doing research. To you I say both congratulations and you suck.â??

My favorite passage might be this gorgeous burst of nostalgia, this prose poem about the bright college years. â??When the check is paid and you stay at the table. When itâ??s four a.m. and no one goes to bed. That night with the guitar. That night we canâ??t remember. That time we did, we went, we saw, we laughed, we felt. The hats.â??

The hats. That tiny sentence was the first raindrop before the deluge, a tickling hint of all that was to come. How many 21-year-olds are capable of a line so sure-handed, so precisely and comically placed? The only other two-word sentence I can think of that had me laughing aloud and shaking my head was in Lolita. (Humbert summarizing his motherâ??s demise: â??Picnic, lightning. â??)

If Iâ??d met Marina, Iâ??d have urged her to keep these first hopeful essays handy, cherish their energy, refer to them whenever beset by despair and doubt. Instead Iâ??ll have to give that advice to her readers.

I also might have told Marina that we do have a word for the opposite of loneliness. Itâ??s called reading. Again, Iâ??ll have to tell her readers. This book reminds us: as long as there are books, weâ??re never completely alone. Open it anywhere and Marinaâ??s voice leaps off the page, uncommonly honest, forever present. With this lovely book always at hand, we and Marina will never be completely apart.
