I had the opportunity to review this in connection with the new edition released by Pan Macmillan on 25th Feb.
I've heard loads about Rainbow Rowell, but had never read any of her books before (I can hear your collective gasping from here.)
I figured 'Carry On' would be the Rowell book I'd be most likely to enjoy, so decided to give it a shot.
I know this is kind of a spin-off of Fangirl (UK - US) - but figured since it was a book based on the fictional series mentioned in Fangirl (so... it's a book based on a series in a book about fanfiction... my head hurts,) that it would be OK to read it standalone (and it was.)
It takes a Harry Potter-esque world and gives it a healthy dose of the 21st Century; it works.
She's not a part of this story - she's a part of her own; so she always feels a little out of place.
That's fine - and, obviously, down to personal preferences. But I can't help but think that with a few changes it could've been something truly special.
And the first quarter-ish of the book is basically Simon having a small pout over nothing and everything. Hold on - it gets so much better!
I also predicted all the twists - it didn't bother me that much, because I was just chuffed that I'd figured it out, but I know a lot of people don't like to be able to figure out plot-points.
There's also a bunch of the usual: some swearing, some violence, etc. If that stuff bothers you then it's maybe not the book for you.
And not everyone is going to appreciate the humour - but, personally, I loved it.
UPDATE: 16th May 2017 - Some people have problems with this book with regards to bisexual erasure. If anyone has any blogposts or reviews which discuss this, please let me know!
