I liked The Wasp Factory but agree with you. There was nothing disturbing in that book. If you enjoyed it, The Bridge, Canal Dreams, Walking on Glass and Complicity are all very good by the same author, especially that last one.
These are all on my to do list. But his sci-fi stuff is unparalleled imo. Sentient starships that travel at millions times C. The guy was a fuckin genius and died too young.
