I've recently started learning about MVC too.
There's a good starting tutorial here: http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/intro-to-aspnet-mvc-4
However, if you want something a bit more in depth, and I recommend that you do (especially if you're coming from a WebForms background, for example, otherwise MVC can seem confusing), then I would look at buying 'Pro ASP.NET MVC 4' by Adam Freeman. I'm only about 100 pages in so far, but it's very good, it goes into just the right amount of detail to give you a firm understanding of what's going on, without overwhelming you with too much stuff that doesn't sink in. It also seems to be the highest rated compared to other MVC books.
