Seen and Unseen
It’s a historical fiction set deep in the Panamanian rain forest. Follow Sam Hildebrand, an ichthyologist, during his harrowing adventure through mud and magic, as he tries to complete the 1911 Smithsonian Biological survey.
Seen and Unseen is fully written and illustrated. The art is a mixture of scientific illustration and monsters, sort of like Spiderwick.
