"With a humorous, accessible tone, Wall, a senior writer for Space.com, answers questions about alien life and space travel...this should appeal to anyone who has ever looked up into the sky and wondered what is out there."

This approach is effective in conveying lots of technical information within a context of manageable scenarios, bolstered by multiple pop-culture references."
