In this collection of poems, noted children’s poet Jane Yolen takes readers on an expedition underground, exploring everything from animal burrows and human creations, like subways, near the surface-to ancient cities and fossils, lower down-to caves, magma, and Earth’s tectonic plates, deeper still below our feet. At the same time, in Josee Masse’s rich art, a girl and boy, accompanied by several animals, go on a fantastic underground journey. This book contains science, poetry, and an adventure story all rolled into one. But it’s also more than that- In these poems we see that beneath us are the past, present, future-history, truth, and story. This thought-provoking collection will evoke a sense of wonder and awe in readers, as they discover the mysterious world underneath us.
