The Dark One
Auror
Every one of my novels has multiple twists and not once have I ever referred to that in an enquiry letter.If there’s a twist to be sure it’ll be in the marketing spiel! Especially if it’s kind of what makes the book. Surely that gets put in the query letter if an author aims for making the twist a major appeal to the book.
Partly because I've mainly done crime and twists are expected, but my historical and sci fi novels have twists also. I've only focussed on the premise when sending off enquiries.
