To Carolyn Driedger (USGS), Leslie C. Gordon (USGS, Ret.), and Professor Barry Voight of Penn State for their technical help with the Rainier eruption.
To my friends Kevin and Jo for introducing me to the town that inspired Greenloop, and to Jo’s brother John for his technological guidance in turning that inspiration into reality.
To Rachel and Adam Teller for their advice on glassblowing.
To Diana Harlin and Jonny Small for their culinary and pop-culture references.
To Nate Pugh for his knowledge of home construction, Cousin Robert Wu for kitchen knives, and Arigon Starr for her navigation through the world of Sasquatch in Native American cultures.

To Major John Spencer (US Army, Ret.) for his military language.
Professor Lionel Beehner (United States Military Academy at West Point) and Major Michael Jackson (US Army) for introducing me to my Bosnian experts.
And to those experts, Jasmin Mujanovic and Leila Disdarevic, who expertly brought Mostar to life.
To my agent, Jonny Geller, who filled some very big shoes.
To my childhood friend Richard Cade, for his unforgettable, second-grade declaration that “Bigfoot is indestructible!”
And, always, to my brilliant, supportive, and superhumanly patient wife, Michelle.
