"When is the best time for fort building? Any time, any season, as explained in this zestful picture book. The busy pages show children skiing, squishing in the mud in the rain, drawing pictures and reading books, swimming,hunting for shells, writing poems, and hiking on trails. Ebullient illustrations in watercolor and colored pencils invite readers to get busy building. The delightfully detailed, colorful double-page spreads spur imagination and enthusiastically embrace fun."--Booklist "This colorful tribute to the perennial childhood occupation of fort-building follows a group of children through the seasons as they use materials at hand to create cozy private spaces.At a time when more children look to screens for their fun, this book might remind them to look around instead."--School Library Journal.
