"You need me to do
what?"
is the amazing opening line that welcomes us into Arctic Sun. Griffin's uncle has asked him to lead a tour group for a week-long trip that's part scenic outdoor Alaskan adventure and part on the ground live-action photography class. Griffin would prefer to stay in the comfort of his cabin, sticking with the routines he put in place to ensure his sobriety, but he understands the need and loves his family, so he steps in to
take his uncle's place as tour guide and goes to welcome the group that's just arrived. One of those guests is
a beautiful blue-haired literal celeb who immediately crushes on him.
And so it begins!
Fair warning: Unlike basically every other Annabeth Albert book, the military plays a very small role in Arctic Sun. Griffin's got a bit of a limp due to an injury from his time in the military, and we're told that he has surgery scars and burn scars on his back and shoulders when River notices them, but there's no discussion or conversation about it.
