The Catholic Woman's Book of Days by Amy Welborn would be a wonderful teacher gift. It's a 365-day devotional written for Catholic women - all Catholic women. It is loosely tied to the liturgical year, is a very handy size, and features special devotions for several saints. It is not structured to be tied to any particular year. So it’s sort of perennial.

While a number of successful devotionals for women have been published for the general Christian market, A Catholic Woman's Book of Days is the first resource in the Catholic market featuring daily devotions and prayers for women. Written by Amy Welborn, the devotional entries are pointed and brief, and help Catholic women connect their everyday concerns with God's Word in the context of their Catholic faith. Each entry is introduced by a Scripture verse and followed by a one-sentence prayer. These devotions and prayers are sure to provide Catholic women with a dose of God's grace each day of the year.
