I haven't read to sleep in a sea of stars, but I read the inheritance cycle 5 times. This was incredibly different than anything of his that I've read, and really I found it depressing, the story hooked me but there is a lot of unanswered questions and it ends strangely. Left me feeling bleak like the main character Alex it was an attention grabber to me at least but then you got to the end and I was just like wow that sucked.
