It is truly amazing what the Skunk Works will attempt to design. From the first operational US jet fighter, to the first operational Mach 2 airplane, to UAVs and suborbital spacecraft (the X-33) ... Skunk Works has tried it all. Normally they succeed, and that is what most books are about. But this one actually takes you into some of the programs that have failed. Although fairly small, it is in full color and contains lots of great information. Highly recommended.

If you want the ultimate (but slightly out of date) book on the Skunk Works, look at the Jay Miller work. However, if you want a good overview that is fairly current, then this is the book for you. It includes data on the UAVs and X-33 that Skunk Works was developing prior to their cancellation. Lots of great photos, mostly in color.
