I’m Luca - Sometimes Invisible: A Diary of Hidden Struggles and Brave Hearts
What if you want to speak — but no one listens?
Luca is eight years old. And he writes.
Not because he has to – but because he has to.
His thoughts, his fears, his quiet hopes find their place in a diary no one knows about.
Because what happens at school, what keeps him awake at night, and what he never dares to tell his big brother Jonas — nobody would understand.
Told through 30 heartfelt diary entries, this sensitive and moving children’s book follows a boy struggling with loneliness, bullying, silence at home, and the wish to be seen.
Between heartache and hope, Luca discovers that even the quietest voices deserve to be heard — and that sometimes, being brave starts with writing it down.
A story for children aged 8 and up – and for everyone who wants to listen.
Themes
– Quiet exclusion and how it feels
– Sibling love that’s silent but strong
– The power of writing when words are hard to say
– Hope between everyday fears and small miracles
Who is this book for?
– For young readers who want to feel understood
– For parents and teachers who want to understand what children often can’t express
– For classrooms, reading circles, or simply quiet evenings filled with empathy
With tender illustrations and childlike doodles that bring Luca’s inner world to life — thoughtful, emotional, and beautifully relatable.
Printed in high quality as a paperback – ideal as a gift or for guided reading sessions.
