As the title hints, “The Dreamers” is less about specific people than about a collective attempt to understand.Īs in “Miracles,” a coming of age novel in which the world suddenly slowed down, Walker is interested in how people respond in a crisis. But, while Walker is ruthless in insisting that the disease strikes at random (meaning: no, being adorable will not save a newborn), she seems reluctant to make us invest too heavily in any of the novel’s dozens of characters.

We get to know a few characters, including a pair of orphaned sisters and Mei, the shy roommate of the first victim. She presents even the most heartbreaking details - such as a single dad who always leaves a window open in case he succumbs, so that passers-by will be able to hear his infant sobbing - as if they’re simply the facts of life in stressful times. Walker is smart not to specify, knowing the setup will send readers’ minds in many directions: Is climate change involved? A supervirus? Government conspiracy? Can we somehow blame it on Putin? In fact, one example of Walker’s light touch, in a novel that could veer toward the heavy-handed, is that she avoids the sentiment it would be easy to wring out of a story in which many of the characters are fated to die. Starting with a student on a college campus and quickly spreading to thousands of others, the unnamed syndrome’s causes are not just unclear they’re barely even considered in Karen Thompson Walker’s follow-up to “The Age of Miracles,” which also dealt with an inexplicable disaster that suddenly shifted the way its characters viewed the world. Something is putting people to sleep, possibly for good.

What is most unsettling about “The Dreamers” is how much is unknown.
