Rats, mosquitoes, bats, cockroaches, leeches, vultures — it’s easy to fear and despise them. But are they all bad? You probably know that rats destroy food supplies and can cause house fires when they gnaw on electrical wires, but did you know their supersensitive noses can help detect tuberculosis or even land mines?

Are these conventionally icky critters really public enemies, or do they have merits worth appreciating? Friend or Foe takes a close look at what we dislike about each of 10 unpopular animals, and then presents the flip side: these very same animals are often smart, helpful to humans and the environment, or inspiring to scientists.

After each pair of polarizing spreads, readers are asked to decide for themselves if the animal is friend or foe. Fascinating research and anecdotes, fun design inspired by propaganda posters, and playful use of persuasive language and point of view make Friend or Foe an engaging read that will leave readers reconsidering common perceptions.
