"Although everyone who has ever had a cold is familiar with the human immune system and its importance, few understand just how complex and intricate the immune system is. In Immune, Internet creator and storyteller Philipp Dettmer takes readers on a journey through the fortress of the human body and its defenses. There is a constant battle raging just under our skin, full of stories of invasion, strategy, defeat, and noble self-sacrifice. In fact, in the time you've been reading this, your immune system has identified and eradicated multiple cancer cells that started to grow in your body. Enlivened by engaging full-color graphics and immersive descriptions, Immune turns one of the most intricate, interconnected, and pervasive subjects in biology--immunology--into a gripping adventure through an alien landscape.
