Anyone who knows me well knows that I'm a huge book reader (mostly technical in content). I love to learn new things, and books present, at least to me, and ideal package. Having said that, you can imagine I get pretty excited when there is a book sale; especially when the discount exceeds 30%.
I'm normally a Borders fan, however Bookpool is having a sale on many new Apress books, all discounted at 45% or more.
I personally recommend the book entitled "Pro C# 2008 and the .NET 3.5 Platform (4th Edition)" by Andrew Troelsen. The very first edition (based on .NET 1.0 beta) introduced me to .NET. Since then, this book has grown to include new framework and language features all the way up to .NET 3.5 and C# 3.0 (2008).
