One hundred years ago. On the foggy Hudson River, a riverboat captain rescues an injured mermaid from the waters of the busiest port in the United States. A wildly popular—and notoriously reclusive—author makes a public debut. A French nobleman seeks a remedy for a curse. As three lives twine together and race to an unexpected collision, the mystery of the Mermaid of the Hudson deepens.
A mysterious and beguiling love story with elements of Poe, Twain, Hemingway, and Greek mythology, drawn in moody black-and-white charcoal, Sailor Twain is a study in romance, atmosphere, and suspense. -Plot summary borrowed from Goodreads
First Second Bress, you're my new Favorite. You've been spoiling me this last year. Anya's Ghost, Friends with Boys, Level Up, American Born Chinese, Zita the Spacegirl... Fantastic. I'm not sure how they keep pumping out some of the best graphic novels I have ever seen, but I am sure that Sailor Twain completely deserves its place in this stable of nerdy goodness.
