From the New York Times bestselling author of My Sunshine Away and The Big Door Prize comes a striking new novel set in a near future America, where a government official goes head-to-head with the passionate—and surprisingly charming—crew of a radical ecological outpost, perfect for fans of Wild Dark Shore and The Light Pirate.

Ella Powell is efficient, focused, and not easily rattled. As a human relocation specialist for the U.S. government, she’s been assigned to L3K, a chain of abandoned oil rigs off the Louisiana coast that have been retrofitted as an ecological habitat for endangered animals and marine life. Her mandate is simple: shut it down. She has five days to secure the biologists’ compliance and arrange new accommodations for the protected species that call L3K home.

But from the moment she arrives, nothing goes according to plan. The L3K crew has no intention of abandoning their work—or the creatures they’ve pledged to protect. Backed by millions of devoted followers on social media, they mount a spirited resistance that Ella is unexpectedly moved by, particularly the pleas from L3K’s head biologist, Graham Flanagan. Ella knows where her duty lies, yet as the deadline looms and the stakes become painfully clear, she finds the line between her orders and her conscience blurring in ways she never anticipated.

Set in a vividly imagined near-future, L3K offers a clear-eyed look at the irreversible dangers of climate change, but also the power of shared community. Both urgent and deeply humane, it is a moving story of defiance, hope, and the resilience of the human spirit.
