Formatting a book and working with returns

I'm working on a project on Adobe InDesign where I am formatting a book and I imported my text from the Gutenberg project website. The text that I am using is from the Adventures of Huckleberry Finn and I am trying to create my own body paragraph style for the text. The problem I have run into is that each line of text has a return at the end of it. When I try to add in a first line indent on each paragraph, because of the returns, it counts each line of the paragraph as the first line and thus indents the whole paragraph. This goes on throughout the entire text and I was wondering if there was an easy solution to getting rid of all the returns without removing the ones at the end of each paragraph to separate one paragraph from another.
