So... I'm not traditionally a YA reader, and I feel a little bit sad about that, because I know there are some wonderful aspects to the YA "genre"... tales dedicated to that age-range, anyway. It's a wonderful age to write about and for, with so many life lessons and issues to learn and navigate through.
That being said, I'm not traditionally a YA reader because, so far, there has always been "something missing" when I've read them. Can I put my finger on it? No... no I can't. It's just not there.
And continuing on with the "That being said..." theme... The "Hidden" series has a lot going for it.
It is an original concept. People being convinced to harm themselves by a magic that manifests through music; an angel-like being that I'm not sure actually is an angel; a hint of romance... or is it?
I really enjoyed the read, and read it quickly (I'm not usually one to read a book in a single day... but there you go). And I enjoyed the second book slightly more (I think it was the greater progress of the romance in book 2 that had me going... yes, yes, I am a sucker for a little romance in my stories).
As I am now reading the immensely popular "Daughter of Smoke and Bone" by Laini Taylor, I'm beginning to feel that readers who have enjoyed that series might enjoy this one... It's hard to say for sure, but I sense enough similarities (but with that, I believe the "Hidden" series is truly original... probably even more so that DoS&B is) to be able to whisper with some hesitation (and I don't make "If you liked this, you'll like that" recommendations lightly), "Yes, yes you will."
"Hidden" is a YA series that I, as a not-typically-a-YA-reader, will continue on with.
