Does anyone have any book recommendations for the newer CCNP Security certification?

I see only the official ones are currently available, does anyone have any information on whether they are good or not?

Is this just for the Core exam or for the specialty as there are about 4-5 exam specialties for CCNP security. Which one where you planning to specialize in?
The OCG for 350-701 has good feedback on Amazon. I remember seeing in the past that printed preparation materials for Security were poor and many people liked to use online video training.
