Bestselling author Christopher Lloyd began his career as a journalist with the Sunday Times newspaper. Then, while camping with his family, he had a critical realisation: even with a 1st class degree in history from Cambridge University and experience as a science writer, there was so much about the world he didn’t know.

So, he set out to write books that zoom out and tell the big stories, opening readers’ eyes to how seemingly unrelated events fit together and showing them multiple perspectives on the world, all in highly engaging prose and matched with lively illustration and photography.

Now, with several books in print, including the bestselling What on Earth Happened? and Absolutely Everything, Chris divides his time between writing books and delivering lectures and workshops to schools, literary festivals, and a wide range of other venues around the world. He lives in Tonbridge, Kent, UK, with his wife and two adorable terriers.
