Dr Samantha Grover is a soil scientist. She and her plant ecologist partner have two young boys who are fascinated by the natural world. Their endless questions and the UNESCO International Year of Soils combined to inspire Dr Grover to create this book to share the wonder of soils with a wider audience.Camille Heisler is an artist and illustrator who lives and works in Melbourne. She is currently finishing a Master in Contemporary Art. As a child Camille became fascinated with the visual world as soon as she received her first pair of glasses. Camille loves colour, making marks and working with light, observing the detail of things. The subject matter of her work often brings into focus the overlooked and the as yet undiscovered. She also loves to read. For this book Camille enjoyed the challenge and wonder of working with pencil and watercolour. She hopes you like the end result.
