Writing a historical novel takes a lot of research, most of which I did on the Internet. Surfing from one site to the next makes it difficult to give credit where it is due, so I offer a general thank-you to those who share their pictures, videos, and expertise. I searched ancient maps, watched boat making on YouTube, and studied old essays for what temperature Antioch would have been a thousand years ago. Any mistakes are my own. Thank you to my fabulous editor, Emily, for making this a stronger book. Christopher and Sheryl, thank, thank, thank you for the last-hour reads.
