Peyton Norelle has closed herself off from the world. Ever since her sister's death two years ago, she has wrapped her heart with chains, protecting and guarding it, ensuring that nobody ever got past her walls. She's just been floating, after having been unable to find the purpose of swimming, nor the willpower to drown. So when Colin Sterling stumbles into her life, she's determined to keep him at arm's length. But that proves to be more difficult than she expected, because soon, after many late-night conversations and early morning laughs, she realises that not only has he become her purpose to swim, he has also - slowly, but surely - taught her the gentle art of healing.
