ABANDONED. Fantasy book about a notebook that connects two different worlds and a female characters who remembers everything she reads

[Kris]

Mallaury, can you tell us more about the heroine - her age, interests/hobbies/skills, personality, rich/poor, family/friends/siblings, parents' jobs, etc.?

How did she get the notebook? (Spoilers are okay - just give us a clear warning before revealing a spoiler - or use the html spoiler tag.)

What's the tone - funny, sad, adventure, romance, etc.?

What's the location - realistic Earth or a fantasy world, time period of the story, etc.?
