A joyous tribute to the many roles one living tree can take--from creating a microclimate to feeding and housing a wide variety of wild creatures. In a mix of lyrical general statements and expansive notes in smaller type, Gianferrari describes how oaks offer a "dining room" for more types of moths and butterflies than any other native tree genus and a winter granary for woodpeckers, which drill holes where they stash acorns. . . . In her painted illustrations, Sudyka envisions a mature tree teeming with wildlife, from googly-eyed bugs to birds and bears--nearly all identified with discreet labels--as well as associated flora, fungi, and, in a final scene, a racially diverse set of young tree lovers. . . . Offers plenty of cause to root for this keystone species.--Kirkus "February 1, 2026"

*Gianferrari and Sudyka explore the many life forms and natural processes--both visible and invisible to the naked eye--that a single oak tree "nurtures and nourishes." From feeding and sheltering wildlife above- and belowground to producing oxygen and preventing soil erosion, and beyond, the oak touches everything around it, forming a micro-ecosystem of its own. Gianferrari's text, with its frequent alliteration, occasional rhyme, and refrain of "just one oak," constitutes an ode to the "beautiful and bountiful" tree's life-giving power. Sudyka's vibrant, painterly illustrations enrich the reading experience, zooming in and out as necessary to put a spotlight on different aspects of the oak-ecosystem.--Horn Book Starred "March / April 2026"

*In a richly illustrated picture book that's chock-full of ecological facts, Gianferrari and Sudyka venerate the astounding oak for its critical role as a keystone species. Employing anaphora, assonant lines highlight the many varied roles a single tree plays for a multitude of species across the seasons . . . Accompanying captions dive deep into adjacent topics, introducing concepts including marcescence (when a tree's withered leaves remain attached) and the brown food web (the recyclers and decomposers who reside in leaf litter). . . . the text goes on to celebrate the deciduous specimen's roots ("farther than/ the canopy is wide"), acorns ("a nutritious superfood!"), and its important functions cleaning air and preventing erosion. Spreads depicting an abundance of goggle-eyed critters washed in watery earthy hues incorporate labels for a field guide-like effect that IDs myriad flora and fauna living in concert with a lone tree. It's a satisfyingly comprehensive and appreciative portrait of oaks and their numerous contributions.--Publishers Weekly, STARRED REVIEW "2/9/2026"
