Newsletter Opt In Site

Hey Noob here. Im looking to make a simple site to get an opt in mailing list for my niche. Im not sure what you would call the style of site but I dont want a bunch of links to content or anything just a page to sign up for the newsletter, then a box for people to put in their name and email. The reason I want this is to market my book, so if there are any better ideas Ill hear them but from lurking on here it seems to be the right direction. So any help would be appreciated, thanks.
