The Official CompTIA® Linux+® Study Guide by Jason Nufryk, Damon Garn, Peter Bauer, Brian Sullivan

4.0

A very good Linux+ resource, and a good Linux resource in general. Since it's web based it's easy to access from anywhere. I do wish the Skillpipe app was still available for phones and tablets, but web works.

Not a full guide to prepare for the Linux+ (XK0-004) but I passed the exam with this, Pluralsight, and working a job that happened to have some Linux based work for a while. I ended up using this book a lot for work related tasks.
