Duluth author Leif Enger’s latest novel, “I Cheerfully Refuse,” is set in the near future in small towns along Lake Superior and on the wide water itself. The apocalypse that’s occurred isn’t some cataclysmic event, rather the novel investigates what could happen if current conditions exaggerate. Citizens are increasingly desperate and illiterate, a billionaire ruling class referred to as “astronauts” (think Elon Musk and Jeff Bezos) employ indentured servants and conduct “compliance” experiments on people in medical ships that roam the seas. Lake Superior is subject to rogue storms and increasing temperatures. The warming waters finally give up the bodies that have lain preserved in icy slumber in its depths. School children have so many behavior problems from toxic chemicals they’d been exposed to in utero, they’re rated on a Feral Comportment Continuum.

Rainy, the narrator, is a bereaved bear of a man and a musician from the small mythical town of Icebridge on Minnesota’s North Shore. (If you read Enger’s previous novel, “Virgil Wander,” Icebridge is right next to Greenstone, the mythical town where that book is set.)

Through a series of unfortunate events, Rainy ends up fleeing Icebridge on a sailboat named “Flower.” Most of the novel follows his Gulliver-like travels to the Slate Islands and Michigan’s Upper Peninsula where he encounters fog, hunger, storms, and lawless townspeople. But there’s also poetic beauty in gulls that settle on his sailboat when he plays his bass, magisterial island rocks, and unexpected kindnesses from strangers. I don’t want to give away too much more of the plot.

Things I loved: The novel’s focus on the importance of music, books and literacy. The sailboat setting, and Enger obviously knows his nautical terms, having had a boat himself in Bayfield, Wisconsin. I also appreciated the hopefulness amidst the horror.

Things I didn’t like so much: The book’s ending. Although it’s beautiful and literary, I expected more after the epic events that led up to it. Once Rainy reaches his ultimate destination, readers are only given a few vague lines about Rainy feeling a slight warm weight against his back, “a pressure like a palm between my shoulder blades.” A few dream-like images round it out and that’s it. But I still think I’ll give it a 5 on Goodreads because the writing is so gorgeous, and we Duluthians need to support each other. The world out there is already cruel enough.

I attended Enger’s Duluth launch last April and noted a contrast to his “Virgil Wander” launch six years earlier. That event was held at a local independent bookstore shortly after Enger had moved here. About 45 people attended and ate brownies and bars made by Enger’s wife, Robin.

His latest launch was held at a local brewery where people’s food order buzzers interrupted Enger’s presentation as their pizzas arrived. I’d say the audience tripled, which is a testament to the connections Enger has developed in the community during his time here. True to the musical emphasis in “I Cheerfully Refuse,” a guitarist accompanied Enger, playing through breaks in his reading.

Enger said he wasn’t sure if he could call himself an actual Duluthian yet or not. As he lies in bed at night, he still thrills at the sound of the lift bridge and ore boats in the canal communicating with each other with their horns. He thinks if he were a real Duluthian, that would all be passé.

I would answer: the trick is holding onto that wonder even after hearing the horns a thousand times. Then Enger will be a real Duluthian.
