EXCLUSIVE: Libby Kay (Nautilus) has joined the cast of USA Network‘s The Rainmaker for Season 2. In a recurring role, Kay will play Megan Grenier, the razor-sharp right hand to cutthroat attorney Amanda Vonn (Merle Dandridge).

Based on the best-selling novel by John Grisham, Rudy Baylor (Milo Callaghan), who is fresh out of law school, goes head-to-head with courtroom lion Leo Drummond (John Slattery) as well as his law school girlfriend, Sarah (Madison Iseman). Rudy, along with his boss, Bruiser (Lana Parrilla), and her disheveled paralegal, Deck (P. J. Byrne), uncover two connected conspiracies surrounding the mysterious death of their client’s son.  

In Season 2, Rudy, Deck and Bruiser face old adversaries and new ones in a case where the lives of hundreds of children hang in the balance, and where winning might be just as dangerous as losing.

Season 1 also starred Karen Bryson. In addition to Dandridge, Austin Nichols was previously announced as part of the Season 2 cast.

The Rainmaker is produced by Lionsgate Television and Blumhouse Television. Michael Seitzman, who also serves as showrunner, John Grisham, Patrick Moran, Jason Richman, David Gernert and Jason Blum serve as executive producers.
