Book Description
‘Too many have suffered at my father’s hands. I won’t let it continue. I’ll stop him, I’ll build a world where we can finally be free, I swear it…’
Berlin, 1938. When Hanni’s beloved sister suddenly vanishes in the middle of the night, Hanni knows her high-ranking Nazi father, Reiner, is not telling her the whole truth and may hold the key to her disappearance.
Years later, after finally learning how to live with her troubled past, Hanni dedicates herself to raising her teenage son, Leo, but her sister is never far from her mind. But when Leo begins to share Reiner’s pro-Nazi views and runs away from home to meet his grandfather, Hanni’s world collapses in an instant. She is determined not to lose her son to her father’s cruelty like she lost her darling sister all those years ago…
Hanni has tried to stop her father before and nearly lost her life. Now she is fighting for Leo too and the stakes are higher than ever. She can’t lose him to the Nazis. She won’t let her father take her son away from her. Hanni knows this is her last chance to bring her father to justice. With her son’s life hanging in the balance, Hanni knows this will be her toughest battle yet. But with Reiner’s popularity stronger than ever, will she succeed?
What I Thought
Her Last Promise by Catherine Hokin is a gripping and heartbreaking World War II novel that explores the power of love and the resilience of the human spirit. The story follows Hanni Winter, who is determined to find her beloved sister after she suddenly disappears in the middle of the night when they were kids. Hanni’s high-ranking Nazi father, Reiner, is suspected to be involved in her sister’s disappearance, and Hanni knows that he is not telling her the whole truth.
The novel is beautifully written and does an excellent job of transporting the reader to various times in Hanni’s childhood as she tries to remember. The characters are well-developed and complex, and their struggles and triumphs are both heart-wrenching and inspiring. Hanni, in particular, is a strong and determined protagonist who will stop at nothing to find her sister and protect her son from her father and the horrors of the Nazi regime.
Her Last Promise is a powerful and emotional read that will stay with you long after you’ve turned the final page. It is a testament to the strength of the human spirit and a reminder that even in the darkest of times, love and hope can endure. It’s the perfect end to a brilliant series of books!
As with the rest of the Hanni Winter books, I highly recommend this novel to anyone who enjoys historical fiction and stories of courage and resilience in the face of adversity.

Author Bio
I seem to have followed a rather meandering career, including marketing and teaching and politics (don’t try and join the dots), to get where I have always wanted to be, which is writing historical fiction. I am a story lover as well as a story writer and nothing fascinates me more than a strong female protagonist and a quest. Hopefully, those are what you will encounter when you pick up my books.

I am from the North of England but now live very happily in Glasgow with my American husband. Both my children have left home (one to London and one to Berlin) which may explain why I am finally writing. If I’m not at my desk you’ll most probably find me in the cinema, or just follow the sound of very loud music.
I’d love to hear from you and there are lots of ways you can find me, so jump in via my website https://www.catherinehokin.com/ or on my Cat Hokin FB page or on Twitter @cathokin
