I had originally taken this photograph in Landscape (as shown here) but when we were brainstorming ideas for the cover, we wanted images that worked together front and back. Ideally, one shot in tropical waters and one in temperate. And we needed space for the text to work around the subject matter. This was a contender from the outset and is actually an image of Mark, the author, freediving with a pod of Atlantic Spotted Dolphin.
