Katherine Heigl is finally back on the small screen, and fans have Firefly Lane to thank. 

The Netflix series—an adaption of Kristin Hannah's 2008 New York Times bestseller of the same name—stars Heigl and Sarah Chalke as two longtime friends who go through major drama over the years, and as the former Grey's Anatomy actress explained on Wednesday, Feb. 3's Daily Pop, she immediately fell in love with the story and the pair at the center of it, Kate and Tully.
