"An obsession with shapes serves as a leitmotif as Frank Lloyd Wright (1867-1959) grows to be a master architect... Neal's stylized illustrations are geometrically anchored, with crisp lines and shapes that occasionally echo Wright's signature patterning, and the earnest, informative narrative centers the subject's relatable interests. Substantial supplemental materials include an author's note, sources, and multiple photos of his work." -- Publishers Weekly
