Silverlight 4 Unleashed?

Laurent Bugnion's "Silverlight 4 Unleashed" has been receiving good reviews. As also, Silverlight 4 in Action by Pete Brown.

Has anyone on C# corner read these books?

Other books I am hearing of are: Microsoft Silverlight 4 Data and Services Cookbook by Gill Cleeren, Kevin Dockx and Pro Business Applications by Chris Anderson.
