Gr 6 Up–The creator of the nationwide coding club phenomenon Girls Who Code provides a top-down look into the world of computer science and women in the field. The author takes a step-by-step approach to teaching the intricacies of coding while keeping the content relevant to the audience (a smart analogy involving a peanut butter and jelly sandwich effectively demonstrates computational thinking). Aided by Tsurumi's humorous cartoon drawings that feature a reoccurring group of five girls, the text takes students through the entire process of a coding project. Saujani stresses the importance of planning, critical thinking, implementation, and debugging. Readers will enjoy the creative freedom the work offers, as sample projects refreshingly don't rely on specific programs. The author concisely explains different subject areas within computer science. A highlight of the book is the sidebar profiles that feature real-life women developing the world of coding, from Pixar's Danielle Feinberg to professor and roboticist Ayanna Howard. VERDICT This timely, well-written title is an excellent resource for budding coders; it bridges the wide gap between simple how-to guidebooks and complex coding textbooks.—Lisa Bosarge, Enoch Pratt Free Library, Baltimore
