The Favorites seems like it has all the elements that could make it a real page-turner: a passionate romance, Olympic dreams, and the drama of a major fallout. Kat and Heath's relationship seems to be at the heart of the story, which could give it a lot of emotional depth. The fact that they go from childhood sweethearts to champions adds a nice layer of tension, and it sounds like there’s a lot of potential for character growth.

The documentary angle is a clever twist, too—it adds mystery and makes it feel like there’s more to uncover. Kat wanting to take control of her own narrative after all these years is an interesting hook, especially since it sounds like there’s a lot of personal and public drama to explore.

Overall, the premise feels promising, but it’ll really come down to how the relationship is fleshed out and how the story digs into the emotional side of things. If the characters and their journey are written well, it could be a really gripping and heartfelt read!
