The Bookbag, a website about new books gives a very good summary of the plot and a positive review, with one irritating nitpick of the type "well if only I'd thought of this, I would have done it better". But you didn't, Jill.
However, it's the reviewer's children who give it the best response, especially when Jill says "my sons and I - even my younger son, the notorious reluctant reader - fairly galloped through it in our rush to find out what happened at the end".
It's the kids' reactions that matter, after all.
The older son noted, "perceptive as ever, that he had thought Hybrids was going to be 'just another' book all about how we should be nice to someone that's different, but it wasn't really about that at all".
She likes the double narrative strategy: "while I don't usually like a book to have multiple narrators, I enjoyed it here. It gave a double perspective on the disease and it also made the love affair between the two much more accessible to pre-adolescent readers."
"We also liked the way the book ended on more questions, not neat solutions."
The summary is: "A sharp, strong and tense debut novel."
The official launch date is 1 May, but copies are trickling into bookshops now.
