A few more review have popped up here and there this Sunday morning. This is what I've found:
Nicola Smith reviews, you've guessed it, Peter Pan in Scarlet for the Independent. ("McCaughrean's book, like Barrie's, is as refreshingly dark and unsentimental as a book about fairies and lost babies can be, and it's hard to see how she could have done it better. ")
Barkbelly, by Cat Weatherwill, is the Washington Post "Book of the Week." (It "has something for readers who love fantasy, folk tales and adventure -- in other words, just about everyone.")
