Lindsey Fraser, who had supplied one of the blurb comments,[15] wrote what is thought to be the first published review, in The Scotsman on 28 June 1997. She described Harry Potter and the Philosopher's Stone as "a hugely entertaining thriller" and Rowling as "a first-rate writer for children".[15][21] Another early review, in The Herald, said, "I have yet to find a child who can put it down." Newspapers outside Scotland started to notice the book, with glowing reviews in The Guardian, The Sunday Times and The Mail on Sunday, and in September 1997 Books for Keeps, a magazine that specialised in children's books, gave the novel four stars out of five.[15] The Mail on Sunday rated it as "the most imaginative debut since Roald Dahl"; a view echoed by the Sunday Times ("comparisons to Dahl are, this time, justified"), while The Guardian called it "a richly textured novel given lift-off by an inventive wit" and The Scotsman said it had "all the makings of a classic".[15]
