Somewhere at Last (Willow's Journey #2‪)‬

While adjusting to her new life on a tiny island, off the coast of Maine, sixteen-year-old Willow Flynn begins to enjoy the hot and carefree summer days most teenagers dream about.
Willow has only two priorities before the start of her junior year of high school: making money at her first real job and spending the rest of her free time with her boyfriend, Michael.
But dreams have a way of crashing, especially when a serious illness threatens the very survival of the boy she has come to love, the boy she’s begun to trust and the boy she cannot live without.
