We were given this by our vicar to form the basis of wedding prep discussions. In fact, the book does most of his hard work for him!
Each chapter addresses a particular topic from three perspectives: your background, your current position, and what may happen in the future. Each perspective then has questions for the couple to discuss. Some of these questions were issues we'd discussed long before; others were issues we'd never even considered.
It's an excellent book for helping you explore each other as complex unique individuals, and for helping you consider some of the questions which may arise weeks, months or even dacades into your marriage.
