Question for the CRRNs: Which book did you use to study for certification?

Hi - I'm seriously considering taking the CRRN in December. I am looking at a possibility of a couple of books which are offered by ARN. Which book did you use and why. I already saw a recommendation for Rehabilitation Nursing: Process, Application and Outcomes, 3rd edition by Shirley Hoeman. There is also a book, the Speciality Practice of Rehabilitation Nursing: A Core Curriculum, 4th ed., by Patricia Edwards.

Did anyone use either of this two books?

Thanks.
