A very old review I recently found:
I bought Letters from the inside in Amsterdam, just before my train departed. I’ve spent the time in the train to read this little book. And I enjoyed reading it. It has been some time since I read this story, but I haven’t forgotten it yet.
I liked the story and Marsden’s writing style. I’m interested in the other books by Marsden. Last week I went to the library and took the first four novels from the Tomorrow-series.
