Kristy Harper Collins, the editor-in-chief of Harper Collins Publishers, is set to join a new writing group for the upcoming season of Big Bang Theory.

Harpel joins a team of writers to tackle episodes from the series which is set for its fifth season on March 31, 2020.

HarperCollins will publish the series’ second season with writer-producer Marc Laidlaw and series creator Chris Carter.

Harbaughs character, Professor Leonard Snart, will return for season five, but the writers will have to contend with new characters like Sheldon Cooper, Leonard Snarts father and the new Sheldon Cooper’s brother, Sheldon Jr., and the first of many new characters to make their debut in the series.

The writers have not yet released any casting information for the new writing team.
