"With a great deal of charm and buttressed by understated humor, Fern tells a fictionalized story of Renaissance architect and engineer Filippo Brunelleschi and his most magnificent work, the dome of the Cathedral of Florence. When word comes out of a contest to determine who will design the dome, Pippo, a goldsmith known for his beautiful but useless oddities, is determined to win and shed his unwanted nickname. The judges decide upon his visionary design but also decree that he must work in concert with his chief rival and primary heckler, Lorenzo. Pippo is dismayed at the prospect of doing all the work and only receiving half the glory, but his determination to see his plan through to fruition wins out. Throughout, [Pau] Estrada's timeless art highlights Florence's orange-roofed architecture and colorfully attired citizens. Readers won't realize just how massive a project constructing the dome really was until they arrive at the scale-shifting detail of tiny workers, scaffolds, and cranes, a scene like something from David Macaulay's The Way Things Work. Although the primary drama between Pippo and Lorenzo is played out with grade-school churlishness, it offers a handy morality lesson: take joy in one's accomplishments rather than the accolades to which they might lead. An afterword fleshes out some of the historical and engineering details of the dome for those inquisitive about the Renaissance."—Booklist (starred review)
