The best book I've read in a very long time and the first ever Bo Caldwell novel for me. I'd never before read anything about missionaries to China, let alone Mennonite missionaries. The saga of hardship and enduring love both Will and Katherine had for Christ, along with their abiding love for each and for the people they ministered to in countless ways is indeed very moving, inspirational and poignant. I highly recommend this book be read by every Christian, especially those who feel called to the mission field.
