"Magnificently researched, brilliantly written, Lethal Tides is immensely entertaining and reads like an action novel. Catherine Musemeche has brought to life the incredible work of the scientists and researchers who made such a remarkable contribution to America’s war effort in the Pacific theater during WWII.” — Admiral William H. McRaven (U.S. Navy, Ret.), #1 New York Times bestselling author of Make Your Bed and The Hero Code

"[An] impressive and inspiring portrait....The result is a rousing account of talent, intelligence, and commitment overcoming prejudice." — Publishers Weekly

"Musemeche fully illuminates the critical yet rarely recognized work of ocean scientists during WWII. The science is compelling and artfully explained, while Musemeche's revelations about the sexism Sears dealt with is particularly stunning. Engaging, intriguing, and surprising, this is a title women's studies and history fans will love." — Booklist

"An engaging, thorough story about a worthwhile subject. This biography beautifully captures the energy, sacrifice, and commitment of military personnel working in the U.S. in the 1940s and makes clear the importance of their scientific contributions to the outcome of World War II." — Library Journal

“Lethal Tides reveals yet another hidden figure of science. In the 1930s, the remarkable Mary Sears made a career in oceanography despite being barred from research vessels because of her sex. During World War II, her knowledge helped turn the tide of war in the vast Pacific Ocean, where submarines lurked, torpedoes stalked, and amphibious landings presented a perilous challenge to a US Navy coping with unfamiliar tides and treacherous coral reefs. Under extraordinary pressure and the highest stakes imaginable, Sears, and the team of mostly women scientists she supervised, charted the way to safety. This full telling of her story is long overdue.” — Liza Mundy, New York Times bestselling author of Code Girls

“This compelling story of the US Navy's groundbreaking first female oceanographer and the team she assembled illuminates how they weaponized their understanding of maritime environments to save the lives of innumerable WWII sailors and Marines. Lethal Tides is dramatic proof of how the best amongst us can have a profound impact in the most unexpected ways.” — Richard Danzig, 71^st Secretary of the Navy
