Actor Mario Lopez was in Houston Saturday along with his sister Marissa signing copies of their new children's book, "Mud Tacos." The story focuses on a brother and sister who find a cardboard box and decide to set up an imaginary restaurant. They end up making "tacos" out of mud, leaves and flower petals.

The siblings were at the Houston Public Library Express at Discovery Green Saturday afternoon.
