I think the Cybersecurity Fundamentals from ISACA is a better study book of the ones below, but pick one that is written in a style that you like.

ISACA Certified in Cybersecurity book

A good study guide, I still like the ISACA one better $50

Certified in Cybersecurity official book

Official ISC2 Certified in Cybersecurity (CC) eTextbook

The official book, lacked a lot of topics when I read it $30

There are not a ton of free study materials for the Certified in Cybersecurity (CC).
