Zest Books, a San Francisco publisher of books for teens, has moved its distribution to Houghton Mifflin Harcourt. The new distribution arrangement will be effective in January 2011. Zest titles had previously been distributed by independent sales representatives.

Hallie Warshaw founded Zest in 2006; the company publishes eight to 10 nonfiction YA titles a year on subjects such as relationships, fashion, beauty, stress, dating, music, and high school and home life.
