"The pacing and format will entice both engaged and reluctant readers; and the exhilaration of a new discovery is captured with a sense of wonder that is sure to inspire children and draw attention to the world of science . . . A winning combination of lyric description, accessible explanation, scientific history, feminism, and accomplishment." —Kirkus Reviews

"Tharp’s work with physiographic diagrams is explained in a detailed and easily understandable way, and the illustrations . . . incorporate maps of the ocean floor. This empowering, accessible account of Tharp’s career serves as a reminder that “sometimes it’s hard to convince people to believe something new”—and shows readers precisely how the groundbreaking Tharp did just that." —Horn Book

"The first-person narration clearly explains the connections between aspects of Tharp’s childhood, controversial scientific theories, and the sexism that kept her from conducting field research. James provides a deep dive into the STEM concepts and the detailed process that Tharp employed to show the world what lies at the bottom of our oceans. Highly recommended for public and school libraries." —School Library Journal

"Using speech balloons as well as standard text, the graphic-novel-style presentation is appealing, and James makes good use of maps, charts, and other images related to Tharp’s work. These are helpful in understanding her findings and their significance. An engaging introduction to Tharp and her significant contributions to geology and cartography." —Booklist
