Wren Cook is the oldest daughter of AJ Cooks children who wants to follow in her mothers footsteps after growing up on the Criminal Minds Set. She fell in love with acting from a young age and along with her brothers played the role of their mothers children on the show. Along with acting she also fell in love with music and her family couldn't be anymore proud especially after the release of her first song. This opened a door for Wren which she could never have imagined when she gets cast as Piper Shaw in the Netflix show Julie and the Phantoms who is the unknown daughter of the living band member. This role was the best thing that could have happened to her due to a certain blonde.
