Sea Change — Diane Tullson

Lucas and his father are not close. In fact they hardly see each other, which is just fine with Lucas. When he travels to the remote fishing lodge his father manages, Lucas is left once again, this time with a lodge worker, a girl named Sumi. She makes it pretty clear that Lucas is on his own. But she does take him fishing and seems to be warming up to him. Then, in a horrible sequence of misjudgments, Sumi is shot in the foot. With no radio and no phone, Lucas and Sumi are truly alone. Fog rolls over the islands and it's up to Lucas to get Sumi to medical help, a day's journey by boat up the inlet.
