Our study group wants to perform a 'Saptah' for Sai Baba. What text is recommended and why is it considered appropriate for a week-long reading?

For performing a Saptah, or week-long reading, the highly recommended text is the Shri Sai Satcharita. Chapter 0 explicitly identifies this work by Annasaheb Dabholkar as one of the few comprehensive and famous works suitable for Parayans and Saptahs. Its suitability comes from its detailed and inspirational nature, which sustains a week-long immersive study. Unlike other brief accounts, the Shri Sai Satcharita provides the necessary depth for such a commitment, allowing your group to engage in a traditional and meritorious form of service and community worship.
