In a matter of decades, a spectacular cold-water paradise thirty million years in the making is succumbing to warming oceans. Kelp forests are largely out of sight, hidden under the ocean’s surface, yet they are one of Earth’s most wondrous and underappreciated marine habitats. It’s an ethereal light-infused realm of sharks, otters, eels, sea stars, crabs, rockfish, and myriad other species vital to a functioning ocean and the countless coastal communities that make their living from the sea. Unlike coral reefs, whose similar plight plays out in tropical waters highly visible to vacationing tourists, kelp forests thrive along cold-water coastlines far from tourist centers. What will it take to stop the decline before these underwater playgrounds bursting with colorful life become vast fields of lifeless urchin barrens?

For readers who know kelp only as tangles on the ocean surface or smelly mounds of seaweed littering beaches, Forest of the Sea: The Remarkable Life and Imperiled Future of Kelp (Princeton University Press, 2026) reveals a thriving three-dimensional underwater world of color and beauty whose loss if allowed to happen will reverberate in unimaginable ways for both nature and humans. David Helvarg, a veteran journalist and accomplished scuba diver, takes us on a memorable journey beneath the waves through kelp’s natural and human history, the billions of dollars of products and services it contributes to our global economy, the unwitting human activities that threaten its survival, and the hopeful movements around the world to restore kelp habitat. Helvarg introduces us to Indigenous leaders promoting sea otter reintroduction, out-of-work urchin fisherman, documentary filmmakers, and ocean scientists all working in an unlikely collaboration to restore and protect kelp forests while promoting a growing range of uses for food, medicine, and energy.

Forest of the Sea is the first book to document what is at stake if we lose these irreplaceable marine jewels, helping readers to understand how these natural systems might adapt and survive.

As Foreign Secretary in Neville Chamberlain's Cabinet in 1937, Eden didn't believe in appeasing the German and Italian dictatorships or the militaristic Japanese regime. Instead, he wanted to confront their aggression head on. Faced with growing Japanese assertiveness, including the launching of an undeclared war on China in July 1937, Eden appealed to the US for help. He believed sending an Anglo-American naval force to the Western Pacific would demonstrate that the democracies were not spineless, but were prepared to stand up for what they believed in. Was this a viable alternative to Chamberlain's appeasement policy, now notorious for its failure in the face of fascism?

In Eden's Alternative to Appeasement: The Anglo-American Strategy that Might Have Been, 1937–38 (Tithebarn Press, 2026), historian Malcolm Murfett tells the story, using a wide range of primary sources from the UK and US archives, of Eden's push to persuade Roosevelt's administration to be more assertive in the Pacific. He reveals the diplomatic dance both sides engaged in, each unsure of the other's reliability, of their own ability to commit, and tied up in their own internal struggles for policy dominance. We get a real insight into how two once-and-future allies managed each other's expectations, as well as the wider strategic parameters within which they were operating.

With eerie echoes of our own times, Murfett explores the challenges involved in both international diplomacy, and foreign and security policy. How standing up for principles and values can become compromised by the requirements of Realpolitik, and logistical constraints.

Nuclear Archipelago: Secrets, Power and the Biggest Atomic Blast in Australia (NewSouth, 2026) tells the shocking story of the two British atomic weapons test series held at Western Australia's Monte Bello Islands in 1952 and 1956. Operation Hurricane and Operation Mosaic took place at a rugged archipelago 100 kilometres off the Pilbara coast, and each of the three bombs sent fallout over vast distances across the country. One of the tests, Mosaic G2 in June 1956, the largest nuclear weapon test ever held in Australia, sparked panic at the time that it had been a nuclear accident. In both the Mosaic tests, the crew of a British ship was deliberately positioned in the path of fallout. The biodiverse natural environment of the islands was left contaminated and has never been cleaned up.

The book explores the politics, the secrecy and the controversies, including the true nature of Mosaic G2 and its role in the clandestine development of the British hydrogen bomb.

Elizabeth Tynan is professor in the Graduate Research School at James Cook University, Townsville. She is a prominent writer and researcher of the era of British atomic testing in Australia. Her book Atomic Thunder: The Maralinga Story (NewSouth, 2016) won the Prime Minister's Literary Award (Australian History) and the CHASS Australia Book Prize in 2017. Her follow-up book The Secret of Emu Field: Britain's Forgotten Atomic Tests in Australia was published by NewSouth in 2022.
