This book is a light-hearted and entertaining mix of light romance and magical fantasy.
At the start of the book, the heroine, Jane Drysdale, has a very ordinary life in Michigan with a dead-end job, supplementing her income by organising the local equivalent of Ann Summers parties. She's driving home when a rabbit runs onto the road and into her car.
Next thing she knows, a group of elves arrest her on a charge of murder, claiming that the rabbit was an elf in disguise. Naturally at first she thinks she's been kidnapped by lunatics wearing Spock ears. But in fact she is has been taken to Sylthia in the magical world of Lowth, and soon finds herself on trial for her life. The only bright spot is her seriously attractive defence lawyer. This is only the start of a series of insane adventures.
There is a lot of very amusing humour, particularly the fact that Jane has a tendancy to outrageous frankness and cannot resist putting into her conversation references to earth films and books which completely confuse the elves, faries etc she is speaking to.
"What do you say to a naked elf" appears to be written more for a female than male audience but if I'm anything of a sample it is funny enough that at least some men would also enjoy it.
I was rather reminded of Linnea Sinclair's books which mix romance and science fiction in a similar way to the mix here of romance and fantasy, except that Sterling's book is several degrees raunchier. Anyone who enjoyed Sinclair's books such as "An accidental goddess" or "Finders Keepers" might quite possibly also like "What do you say to a naked elf", and vice versa.
