Nora Grey is your average high school overachiever, with an almost entirely average life. Until she is paired with Patch for a biology assignment. Nora finds herself frighteningly attracted to him and terrified by his strange confidence and almost telepathic ability to know what she's thinking.
Soon she discovers that Patch is a fallen angel who wants to become human. She can't decide whether to fall into his arms or run away... but time is running out, and she may not have a choice in the end...
Here's the thing: in a general sense, Hush, Hush is a great book. But I'm a nitpicker. And there's a lot of things the reader is either supposed to ignore, not notice, or suspend their disbelief for. And I don't like that. Hush, Hush is one of those books where it seems like the author herself didn't notice these details.
So, yeah. The detailing aside, I did like Hush, Hush fairly well.
See above comment about the suspension of disbelief. There's so many holes in the plot! Seen from far off, Hush, Hush has a really cool plot. But when you read it and pay attention... well... the premise is cool; the execution, not so much.
Nora and Patch seemed like just another Bella/Edward, Grace/Daniel, human/supernatural YA couple of your choice. Neither offered anything really exciting or new. I was actually disappointed; I'd heard very good things about the characters and specifically Patch. But I don't think any of the characters are anything special. In fact, I downright disliked many of the side characters.
If you ignore the holes everywhere, Fitzpatrick is actually pretty talented and the writing is quite good.
End Result: three stars. A decent book, but not amazingly excellent.
