Does anybody know of good (or any) Microsoft Dynamics Crm 2011 developers book?

I'm managing just fine till now with the SDK and everything, but still it will be great if there was a book that speaks the humans language and gives real perspective (in appose to Microsoft perspective) on developing for Dynamics CRM.

There's this list http://blogs.msdn.com/b/crm/archive/2011/02/01/microsoft-dynamics-crm-2011-book-club.aspx but (if I'm not mistaken) none of the developers books came out yet.

Please comment when you find one...
