Seaglass Promises in the Midnight Sky

How quickly can you fall in love with someone? Some people say it only takes a day, a moment. For Lorraine Michaels, it took one summer.
(Disclaimer: I took events from both the show and the first book, doing my best to find a happy medium. Additionally, because I personally do not feel it's appropriate to write a love story while Conrad's character is going through such a vulnerable time, I removed the plotline of Susanna's relapse with cancer.)
