I generally enjoy Matt Haig’s books, and saw they were making a film of this so thought I’d read the book before it came out. What I didn’t realise ’til I started reading it, was that it’s a vampire book, which isn’t really my cup of tea.
The Radleys seem from the outside to be an ordinary family – but actually, they’re vampires. The parents choose to live as abstainers – not consuming any blood, not human, nor vampire. The two teenage children don’t yet know that they’re vampires. Of course, the plot comes from them finding out who they are in rather dramatic circumstances and the fall out from that.
It still felt very Matt Haig to read, and the story itself was fine, easy to keep interested, it’s just not really my genre.
The trailer for the film is below:
