I wish they had an “amusing” section for books the are funny but through prose, not “comedy” deliberately trying for jokes etc. Satire might be a category but generally has too much bite to be exclusively amusing.
Larry Niven – A Mote in God’s Eye, but probably like Lucifer’s Hammer the best. He wrote with Jerry Pournelle that are excellent. But he is probably most famous for his Ringworld series that he wrote solo.
Kelly Greenwood – recently discovered after seeing her books produced for Australian Public Broadcasting. My favorite is the Phryne Fisher Mysteries series that takes place in Melbourne in the 1920s where the impact of WWI was still resounding.
