Sometimes life can change in an instant. Martha Boyle and Olive Barstow could have been friends, but they weren't. Weeks after a tragic accident, all that is left are eerie connections between the two girls, former classmates who both kept the same secret without knowing it.

Now, even while on vacation at the ocean, Martha can't stop thinking about Olive. Things only get more complicated when Martha begins to like Jimmy Manning, a neighbor boy she used to despise. What is going on? Can life for Martha be the same ever again?

For fifteen-year-old Haven, life is changing too quickly. She's nearly six feet tall, her father is getting remarried, and her sister—the always perfect Ashley—is planning a wedding of her own. Haven wishes things could just go back to the way they were.

Then an old boyfriend of Ashley's reenters the picture, and through him, Haven sees the past for what it really was, and comes to grips with the future.

During the summer of her divorced father's remarriage and her sister's wedding, fifteen-year-old Haven comes into her own by letting go of the myths of the past.
