So this is indeed a new series, seeing as it was recently published.
So far, I've only read the first book, (The Iron King), but it's a book to fall in love with.
The story is about a young girl that notice strange things happen on the day of her sixteenth birthday. She learns about the other half of the world, which happens to be a Faeryland, a place of exotic creatures such as faeries, and a place giving adventure to those daring enough to enter. Once she is introduced to the world, she realizes why she is the key to winning a deadly war.
Don't get me wrong, I do find the fairies imagined up alright, though the fairies described in this book are nothing to ever be imagined before.
.. Yup, Got to love that snail mail! ROFL Escargot anyone? ^_^
