Another author boosted by ‘Colbert Bump’

The “Colbert Bump” is becoming contagious.

Edan Lepucki, whose novel California became a best-seller thanks to a plug from Stephen Colbert, has in turn helped another book catch on.

During an interview on Comedy Central’s The Colbert Report that aired on Monday night, Lepucki recommended Stephan Eirik Clark’s Sweetness #9. By Tuesday morning, the novel was in the top 300 on Barnes & Noble.com and in the top five for Powell’s Books, an independent store based in Portland, Oregon, that has been a leading seller of Lepucki’s book.
