The Butterfly Box (by Nora Naish)

(Amazon UK link)

I've never heard of Nora Naish, and can't find anything about her on the Internet (other than lists of her books, and a few book reviews). However this was another of those books that looked good from the cover and blurb on the back. I found it in a second-hand bookshop...

'The Butterfly Box' opens with Lucy's 80th birthday. There's a family reunion, with some inevitable tensions.

An old heirloom, a box with a secret, is opened. Then there's a very lengthy flashback to the past, which gradually uncovers an unpleasant family secret.

However, by the time it was revealed, it was no surprise to me. I didn't find the book terribly interesting, really.

No longer in print, but perhaps worth picking up if you come across it inexpensively in a charity shop.
