>>12765835The George F. Simmons precalculus book is like 100 pages but it's hard to find a good ebook copy. The college I TA at uses a book by Jon Rogawski, and it's got like 50 pages of precalculus review. Just download a few Calculus textbooks and see which one you like best. Some common ones are Larson, Stewart, and Rogawski. Though, the suggestion of Lang isn't a bad idea either if you want something more comprehensive.
