Remy thinks life after high school will be easier. He’ll go to California Pacific for a year while he gets a handle on his HIV, then after Michael graduates from high school, they’ll blast out of there for colleges—and life—on the East Coast. Then Remy visits Boston and everything changes. He realizes he likes CalPac. Turns out, Boston doesn’t have anything for him beyond one of the biggest regattas in North America.
