Dictionary meaning

a person who is completely transparent, with no hidden aspects, secrets, or undisclosed motivations — everything about them is readily visible and legible to others; contrasted with the more guarded person who is difficult to read or who conceals their inner life, the open book is characterised by a candour and transparency that makes them easy to know, easy to trust, and sometimes easy to underestimate; the phrase can be used positively, to describe someone whose honesty and transparency are refreshing virtues, or with slight condescension, implying that the person lacks the interiority or complexity that makes someone truly interesting to engage with over time
