Book Description
For Lewis and Wren, their first year of marriage is also their last. A few weeks after their wedding, Lewis receives a rare diagnosis. He will retain most of his consciousness, memories, and intellect, but his physical body will gradually turn into a great white shark. As Lewis develops the features and impulses of one of the most predatory creatures in the ocean, his complicated artist’s heart struggles to make peace with his unfulfilled dreams.
At first, Wren internally resists her husband’s fate. Is there a way for them to be together after Lewis changes? Then, a glimpse of Lewis’s developing carnivorous nature activates long-repressed memories for Wren, whose story vacillates between her childhood living on a houseboat in Oklahoma, her time with her college ex-girlfriend, and her unusual friendship with a woman pregnant with twin birds. Woven throughout this “heart-wringing” (Adam Roberts, internationally bestselling author of Salt) novel is the story of Wren’s mother, Angela, who becomes pregnant with Wren at fifteen in an abusive relationship amidst her parents’ crumbling marriage. In the present, all of Wren’s grief eventually collides, and she is forced to make an impossible choice.
Notes & Highlights
April
As Lewis held Wren’s hands, he thought of her kindness, her intelligence, her inner beauty. Yet, just as he married these known qualities, he also married her vast unknowns. And she, his.
Scene: Lewis’s Fourth Vision
As their saltwater tears combined with the sea, Lewis finally understood the log line of their love story: He was an aimless kite in search of a string to ground him to the world, but instead, he’d found Wren, a great, strong wind who supported his exploration of the sky.
Joy, Age Six
Wren no longer sees life as a long, linear ladder with a beginning, middle, and end. Instead, she considers how life is like a spiraling trail up a mountain. Each circling lap represents a learning cycle, the same lesson at a slightly higher elevation.
