Tomorrow #1 is a fun young adult book that keeps up the suspense and scariness of these teens' new existence. I enjoyed it, but wouldn't say it's my favourite.
It deals with many real issues teenagers face in a more realistic way than some other books though, which I liked. Sometimes it's just a bit too much though.
Also, in the Kindle edition the proofreading is terrible as a lot of punctuation marks are simply missing. However this doesn't detract too much from the story.
A fun read!
