Rounded up from 2.5. The story was pretty interesting, but the prose style was amateurish. I know that it's aimed at younger audiences, but just because you need to simplify doesn't mean you can't write well, and with style. I did enjoy the plot, and the pacing was good. The characters were mostly 2 dimensional, but maybe that is to be expected given that all of them have lost the memory of their old lives, starting fresh when they arrive at the Glade, remembering no detail but their name. There were also a couple of contrived plot points where the brainy protagonist completely fails to figure out a glaringly obvious fact. He is smart enough to decipher some complicated things, but fails to make very simple connections, and that took me out of my disbelief suspension. It was a page-turner, and I do plan to read the rest of the series. I hope that the writing improves, and maybe it will. People can get better.
