"Ken Thompson builds a careful, documented, detailed case with copious examples; smooth, factual, wry and humorous writing; an ecologist's training but a journalist's writing. His explanations are accessible, and very entertaining. ...This clear-eyed, lucid, conversational essay securely asserts that our focus on native or alien is misguided" Five stars —San Francisco Book Review
"Fascinating, provocative... Ken Thompson presents a stimulating challenge to our perceptions of nature"George Monbiot
"The information he presents is compelling. ...This title brings an important minority opinion to light"School Library Journal
Thompson makes his case in a lively, readable style, spiced with a healthy dose of sarcasm towards "aliens = bad" fundamentalists. Better yet, he bolsters his argument with plenty of citations from the scientific literature, which adds welcome heft.” New Scientist
"A well put together book about the science and the philosophy surrounding invasive species"The Times
"Lively and punchy
you walk away from this book feeling flushed and a bit bruised. Thompson’s arguments are powerful and his examples are fascinating”The Sunday Times
