(4) 4-6 STEM Trailblazer Bios series. These volumes give brief, superficial overviews of the lives and accomplishments of "trailblazers" in the fields of science, technology, engineering, and mathematics. (From McGonigal: "Just before they left for college, they finally beat the game! They treated themselves to frozen yogurt to celebrate.") "Tech Talk" sidebars provide more information. Photos of the subjects (and some awkward stock images) break up the texts. Reading list, timeline, websites. Glos., ind.
