Tempest

There's plenty of violent action in Tempest, but because of time-travel paradoxes, hardly anyone ever ends up permanently injured. For example, Holly is shot at the start of the novel, but healthy versions of her appear in different timelines throughout the rest of the book. There are gunfights and fistfights, but blood and pain are barely part of the equation.

Jackson and his girlfriend Holly are depicted as having a fully sexual relationship, and it's implied that Jackson, at least, has had experience with other partners. There are a few scenes that deal with their physical intimacy, including the night Holly loses her virginity (at age 18). Jackson's father seems to have little problem with female guests spending the night in Jackson's room. No sexual acts are described in detail, but the characters sleep and shower together. There's also a lot of flirty banter between Jackson and Holly.

Characters use profanity rather casually, not only in moments of extreme stress but in friendly conversation. "F--k" is employed in only a couple of instances, but "s--t," "a--hole," and their variants are used more often, as are "damn" and "hell."

Underage drinking is discussed but not depicted.
