Celebrity chef, author and Food Revolution host Jamie Oliver has jumped to HarperCollins’ Ecco imprint after working with Hyperion on earlier books.

Ecco will publish the first book in fall 2014 with another book coming one year later. The publisher did not reveal the subjects of the books. According to the release, the chef sold more than two million copies of 30-Minute Meals in the UK. Oliver had this statement about his change of publisher:

I’ve been incredibly fortunate to have worked with such a supportive publisher in Hyperion but I am really excited about this new relationship.  It is an honor for me to join the company of the great chefs on Ecco’s roster.  Many of them are my friends and I look forward to this partnership.
