Sullivan's Crossing has been following Maggie Sullivan (Morgan Kohan) and Cal Jones' (Chad Michael Murray) romance for three seasons, but now that they seem fully committed to each other and the Crossing, it's hard not to feel like some of the central tension of the show is gone. The CW TV series is based on the series of novels by Robyn Carr, the bestselling author of Virgin River. However, in the Sullivan's Crossing novels, Maggie's love story is only the focus of the first book.
