A tragedy has sent a young artist into seclusion. A potential apocalypse may be enough to bring her back. For the past two years, 10 months, and 18 days, Katie's lived in darkness, on retreat from her former life as a rising artist after a personal tragedy eclipsed any happiness she believed possible. Jacob's Ladder, a remote island named by a former resident for its potential as a stairway to heaven, offers Katie the chance to hide from the rest of the world, merely existing, not healing. She lives each day trying to fulfill what she's called "the Promise" to those in the life she once knew, though a promise of what is not clear. The closest neighboring islands, Oak Haven and Ringrock, are equally cloistered. Though Katie's realtor has suggested that Ringrock is some sort of Environmental Protection Agency research station, Katie's cynicism makes her suspect something more nefarious. The protagonist's remote world and the author's moody writing are disrupted one night by the startling appearance of drones and the suspicious behavior of a fox Katie's dubbed Michael J. The wary canine serves as a harbinger of potential danger, and Katie responds by arming herself to the hilt when unexpected guests descend on Jacob's Ladder. While the true purpose of these visitors is unclear, Katie senses that the greater world is at the precipice of permanent collapse and that she may be the only one who can prevent the impending apocalypse. A moody tone hangs like a cloud over the alarming but vague danger awaiting the world. Copyright (c) Kirkus Reviews, used with permission.
