Who says you can’t choose your family?

Their shared sweet-16 party is just around the corner, and half-sisters Isabelle Scott and Mirabelle Monroe are ready to cut loose, even if they are the daughters of a prominent public figure. So when Izzie’s estranged aunt, Zoe, breezes into town unannounced, it just might be the change that the Monroe family needs - or not, depending on who you ask.

Happy with her cute surfer boyfriend and a group of great girlfriends, Izzie has no interest in getting to know yet another long-lost family member. But Mira, who’s on a mission to try new things and meet new people - a handsome brooding painter in particular - is drawn to Izzie’s artsy aunt, who seems to be the polar opposite of the uptight Monroe family.

As the girls try to negotiate the unexpected paths their lives have taken, Zoe’s laid-back attitude eventually charms them both. But when Zoe offers Izzie the chance to leave Emerald Cove and start fresh in California, Izzie and Mira are faced with bigger changes than they expected. Is a move to the West Coast what Izzie had in mind for her sweet 16?
