From Aiyaya to Alleluia brings us on Tek Seng and Tinkie's life journey as they find faith after a family crisis, negotiate through several economic downturns while managing a business, maintain harmony in their marriage while working together, and discover the joy of ministering together as a couple. From despair and discouragement ("Aiyaya") to faith and praise in God ("Alleluia"). This book ends with a 30-day devotional by Tek Seng, which had helped him through one of the most difficult seasons in his and Tinkie's life.
