When a wealthy family invites Sallie Riehl to be their daughter's nanny for the summer at their Cape May, New Jersey, vacation home, she gleefully accepts the opportunity to broaden her horizons beyond the Lancaster County Amish community where she grew up. Sallie always dreamed of seeing more of the world, but her parents are weary of putting off baptism for another summer. The timing is most unfortunate for Perry Zook, who is once again interested in courting her.
While she loves her job as a nanny, Sallie invests her free time on the weekends on the sea shore. There she meets Kevin Kreider, a marine biology student who speaks freely about what he is learning and takes an active interest in where passions. The invigorating time she spends around Kevin leads Sallie to realize she has never felt this way around Perry. As a greater challenge to her heritage, Kevin is Mennonite, not Amish.
Sallie fights past her growing feelings for Kevin, fearing what her parents might think about her new friendship. She's also realizing her time in Cape May is increasing her desire to see the world. Has she been too hasty with her promises, or will Sallie discover her heart truly does long to return home to Paradise Township?
