Young Grey Anderson, an American girl, journeys to the South of France for an ""all-alone, out-on-your-own adventure"". She checks into a lonely room in Cannes. Thus begins that ""something"" which she sensed would happen to her. She goes to the beach. She meets a boy. She falls in love with the boy and loves the boy. She and the boy part, but not before they talk a great deal ""in half-sentences"", drive in an open sports car through France, swim and sun and parch together. In capturing the sun on the air, the languor of basking bones, Miss Sevier is very good indeed. It takes, unfortunately, more than an extended mood to make a novel and more than fragile sensibilities to make a lead character go anywhere or mean anything. Most importantly, it takes a couple of the techniques of enchantment to bind a reader. One hopes young Miss Sevier will go on to sturdier stuff.
