Big Two-Hearted River (Parts I and II) Steaminess Rating

Exactly how steamy is this story?

G

There is no sex in this book, no violence (unless you count the implied violence of the war, or the violence of gutting a fish), and no crude language except when Nick eats his dinner before it’s cool (because he’s a hipster) and says “Geezuz Chrise.” Sorry to disappoint you, kiddies.
