I am currently reading Sandcastles of Love by Sydell I. Voeller.
When Logan Becker’s family embarks on a summer “house swapping” vacation in a beach town in Oregon, Logan is overjoyed. Similarly, Tricia Merrit, the daughter of the other family, is thrilled to be in the farm belt of Minnesota.
Logan falls in love with the beach boy surfer of her dreams, but soon she discovers he’s Tricia’s boyfriend. Logan’s dreams are shattered. Meanwhile, there’s another boy who is attracted to Logan—the totally uncool Grant Duncan who is busy trying to launch a campaign to clean the local beaches. Can Logan come to realize that true love often reveals itself in unexpected ways?
