The gentle, contemplative touch of the poet is evident in the rhythm and fluidity of the language and bolstered by the work of Sís's encompassing and elegant illustrations–a layered mix of watercolors, pen, and ink that pair beautifully with the spare and delicate poetry. His art, like Limón's writing, is rooted in the elements but threaded through with magic... The book, while fairly brief, reveals something new upon each reading: a testament to the wonder and mystery that Limón writes about so movingly. This would be a lovely and innovative addition to a classroom lesson on space exploration... This ode to beauty and the still-to-be-explored corners of the universe will find an audience among elementary school students and educators.– "School Library Journal (starred review)"
