open-book

Hiding nothing whatsoever

Open-book describes a test or exam where students may consult their notes, textbooks, or other materials: The final was open-book, but it was still brutal.

By extension, an open book is a person whose thoughts and feelings are easily read—transparent, hiding nothing: She's an open book; you always know where you stand with her.
