Small-town nurse Nina Wentworth has made a career out of being a caretaker. More "Mom" than their mother ever was, she sacrificed medical school -- and her first love -- so her sister could break free. Which is why she isn't exactly thrilled to see Averil back on Blackberry Island, especially when Nina's life has suddenly become…complicated. Nina unexpectedly finds herself juggling two men -- her high school sweetheart and a younger maverick pilot who also wants to claim her heart. But as fun as all this romance is, Nina has real life to deal with. Averil doesn't seem to want the great guy she's married to, and doesn't seem to be making headway writing her first book; their mom is living life just as recklessly as she always has; and Nina's starting to realize that the control she once had is slipping out of her fingers. Her hopes of getting off the island seem to be stretching further away…until her mother makes a discovery that could change everything forever.
