At my high school, they introduced us to Faulkner with SANCTUARY. I never returned to him until this summer, when somewhere or other I picked up a copy of this, Faulkner's last novel, published a month before he died in 1962. The following year, it won a Pulitzer, yet it is one of his least-known works.
I am convinced this is the novel with which to introduce readers to Faulkner. It is set in the fictitious Yoknapatawpha County that is the setting of several of his novels, a landscape with a rich geneaology of characters.
For his last novel, Faulker wrote a delightful coming-of-age "reminiscence" set in 1905 - funny, wise, and wistful in tone, with some excellent characters. In particular, note the complexity of the relationships between white and black characters throughout.
The prose is distinctly Faulknerian yet more linear and accessible than some of the bigger works from which Faulkner earns his more intimidating reputation. It may not be considered one of his masterpieces, yet it is funny and touching, excellent quality, and enjoyable to read.
