It was the fastest read i had lately, exactly like a YA read, but this is well written, it's packed with references and it made me want to read the origin of species!
There are a few elements that could annoy some (say the relationshiop between Matthew and Diana that eerily reminds of Edward and Bella/Ana and Christian Grey)(domineering alpha male/obeying fast mouthed girl) but i love it nonetheless.
It's entertaining and yet more mature than the aforementioned and fun, good read.
