Thread: ...есть чему удивиться.

Can someone translate the following?

- Объединённые в этой книге дневники актрисы, по словам издателя, не предназначались вначале для опубликования, поэтому читателю есть чему удивиться.

Perhaps it is something along the lines of:

The combined journals in this book, by the words of the publisher, were not meant to be published at first, so the reader has something to be amazed at.

The actresses diaries incorporated in this book, according to the publisher, were not meant to be published at first so the reader has something to be suprised at.
