If you, as a teenager, won a lottery to visit the moon, would you take the trip of a lifetime?

Norwegian author Johan Harstad creates such a scenario, and has three teen winners from around the world agree to set off on what’s billed by NASA as an amazing space adventure. In his young adult book, “172 Hours on the Moon,” the three eventually find themselves trapped in a horror story as they try to survive a brutal environment and a sinister force bent on their destruction.

Harstad is coming Wednesday to Copperfield’s Books in Petaluma for a Sci-Fi Pizza Party,  a chance for teens to “eat, drink and be literary.” The author event takes place at 7 p.m. at the store, 140 Kentucky St.

I’ll be the moderator for the questions-and-answer portion of the evening.

Harstad, an author, playwright and short story writer, won the Norwegian Brage Award in 2008 for the book, which in his country is titled, “DARLAH,” the name of a Moon base in the story. The U.S. edition was released as “172 Hours on the Moon”  in April by Little, Brown and Co.

From here, Harstad will be going south to Comic-Con in San Diego.
