A band of intrepid explorers embarks on a voyage through a strange frontier filled with mystery and beauty: the human body. Donning his frock coat and ruffle collar, Tusseson documents everything that happens in his logbook: traveling by boat across the Stomach's Stormy Sea, paddling through the Small Intestine's Emerald Green Canals, camping at the Lungs (despite all the wind!), climbing the Muscle Mountains, escaping through the Nerve Forest to marvel at the night sky, Iris, reflected in the Pacific Tear Channel. As his fellow travelers return home one by one, Tusseson is left to carry on alone but he won't give up until he finds the Mystical Meadows of the Brain. Featuring lush and surreal illustrations, The Expedition renders the systems of the human body into wondrous landscapes that take readers on a fantastic voyage like no other.
