Pathfinder (novel)

Pathfinder is a 2010 fantasy/sci-fi novel by Orson Scott Card. There are two parallel stories: The main plot concerns Rigg, a boy with the ability to see "paths" left behind by all living creatures when they move, and how he gets caught up in a political struggle for the fate of the known world. The second story deals with Ram, the pilot on a colony ship heading out from Earth to colonize a new world, equipped with an experimental hyperdrive, and his interactions with the ship's computers and the Expendables, a group of androids that interface with the computers and serve as advisers.

Fairly early on Rigg learns that he's not the only one with unusual powers, and that there's a way to use his ability to not only see the course of people and other life from the past, but to interact with them and change the past as well. So of course many Time Travel Tropes get used, though the author's note explains that he wanted to "embrace" paradox rather than avoiding it, so expect to see the Time Travel Tropes get played with.

Beware. This is an Orson Scott Card book, and so of course the plot gets very twisty. Even reading the trope example names could result in spoilage. -

Pathfinder contains examples of:

 * Achilles Heel / Attack Its Weak Point:  So not cool!
 * Affably Evil:  General Citizen has a bit of this vibe to him at first too.
 * Ancient Artifact: Turns out one of the gems Rigg's father gives him was  Also, it turns out that
 * Artificial Human: The Expendables.
 * Bullet Time: No actual bullets, but  has the power to make people's perception of time speed up or slow down.
 * Cloning Blues:
 * Colony Drop:
 * The Cretaceous Is Always Doomed: Justified. Rigg can travel back in time by identifying the "path" of a living thing that had walked the land before. In a moment of urgency he picks the most recent path of an extinct animal he sees, which turns out to be fleeing the Colony Drop that rendered it extinct.
 * Does Not Like Shoes: Rigg and Umbo, according to a line by Loaf.
 * Expy: The character of Rigg bears a strong resemblance to Ender Wiggin, due to their precocious intelligence and snarkiness.
 * Fluorescent Footprints: Rigg's power of tracking "paths".
 * Force Field Cage: The Wallfold that surrounds the known world is made up of an invisible force field-like Wall that doesn't physically prevent you from entering, but does fill any living being's mind with overwhelming dread if they don't turn back, eventually driving those who try to cross insane.
 * Humans Are Psychic in The Future:
 * I Am Who: Poor Rigg. His dad never told him he was  or what the political ramifications of making that known would be.
 * No Biochemical Barriers: Averted and discussed in the colony ship subplot.
 * Parental Abandonment: The story starts off with Rigg's father, who had raised him alone his entire life, dying when a tree falls on him.
 * Peoples Republic of Tyranny: The People's Revolution has some elements of this.
 * Reasonable Authority Figure: Loaf plays this role for a lot of the story.
 * Ripple Effect Proof Memory: This happens to Rigg when he changes the past. Other people's memories change, but his doesn't. This can be inconvenient at times, if a change he made altered history and he's not familiar with the influences it had on modern culture.
 * Signature Style: It's an Orson Scott Card book. Expect plenty of snarkiness from precocious children. Also, at the beginning of each chapter except the first is a short "header" telling a part of a side story.
 * Time Travel Tense Trouble: Pops up all over the place.
 * Timey Wimey Ball: Trying to keep all the time travel straight gives the characters who were involved a headache. It can be even worse for the reader.
 * World of Snark
