Castro Valley Reads 2025
Castro Valley Reads is a community-wide literary event encouraging people to read and discuss the same book. This annual program celebrates the thoughtful exchange of ideas and the joy of reading together.
In addition to discussion groups, the program includes special events inspired by the themes in the book and a chance to meet the author.
For 2025 we will celebrate Mexican-American history and culture through a fast-paced, raucous family saga.
