I love dystopian YA fiction and was excited to read this because the premise sounded realistic and interesting. Unfortunately the writing let it down in a big way. I found the characters' voices inauthentic, and the storytelling flat and unconvincing in many places.
The diary format can be used to such great effect (and within the dystopian YA genre: see Life As We Knew It: Our world ends tonight (The Last Survivors), a fantastic book) but here Lloyd seems to use it as an excuse for shallow, unimaginative writing. She also seems heavily influenced by the Adrian Mole books, lifting phrases like 'dead passionate kissing' which don't fit with the author's own style, such as it is.
I found it difficult to care about Laura, and agree with other reviewers that the 'street talk' was grating. The tone swung wildly between what the author seems to think 'the kids' talk like, and more straightforward language.
I'd have loved to have read this book written by someone better. Sorry, Saci!
