I'm a Wrox man myself, so any of their books would be mint.
HOWEVER, one thing to note: If you're using Visual Studio to do your asp.net, then hold off a bit. All the books out there so far all deal with asp.net in an old school way (i.e. adding script tags to an html file), instead of using Visual Studio.NET, which is a different development environment froma text editor all together.
If you just want to get your head around the basics though (like what ASP.NET is, how it works, etc.), then Beginning ASP.NET using VB.NET from Wrox is an excellent pick. Its what I used to get my jump start into developing with asp.net
