Short and blunt: Precalculus With Limits: A Graphing Approach (Advanced Placement Version) 4th Edition is overhyped but not bad. What worked: the first third is sharp, tense, and weirdly funny. What didn't: it can't stick the landing, and the big reveal feels like a cheat. Recommend for people who like the ride more than the destination, skip for anyone who hates loose ends.
