A pleasantly ambient first novel pursues the uneven course of love in the proposed marriage of Elizabeth Whitacker, a widow and an Anglican, to Michael, a Roman Catholic. But Michael's devotion is tried to a point past patience by Elizabeth's indecision over the problems of a mixed marriage, and while often an indolent and skeptical believer in her own faith- she finds herself reluctant to make any concessions to the demands of his. A first break between them leads to a reconciliation, whetted by his squiring of another girl. Elizabeth agrees to marry him and receives instruction from a priest with boredom and a growing irritation. And the final admission that she cannot marry Michael brings its welcome release, and the reassuring prospect of another man's awkward but unfaltering affection.... Elizabeth's family and friends, the pupils at the fashionable school where she teaches, all make up a tasteful needlepoint of incident and sentiment in what is essentially an unruffled romantic novel.
