The Hook may be the most important part of travel writing, especially creative travel writing such as poetry. Not only should the focus be on grabbing the reader's attention, a writer's goal should be to ultimately transport the reader to that particular place. They should see and hear and feel everything the writer does. Poetry has taught me the same lesson; set the scene. Without that, everything can fall apart. What is most interesting is that this particular move generally has the same function across the board without the exception The function is to grab the readers attention and draw them into your writing. One could argue this is because the beginning is the most important aspect of any writing. If your beginning isn't interesting enough, no one will ever get to the meat of your argument or idea or poetry.
