Coe is the rarest of autors who can seamlessly straddle between mainstream appeal and creative genius. There's enough symbolism and metaphors to keep those who like to dissassemble their novels to gather meaning yet these symbols and metaphors never overshadow the main story, much to the content for those who don't care for such symbolism.
From the characterisations to the very way in which Coe controls his prose (and breaks the rules of conventional grammar in what is the most moving sentence I've ever read), the Rotter's Club is the reason why we read books and that is to find a story that touches us in such a profound way that you cannot irrevocably be the same again.
