Laurie Faria Stolarz is a GREAT Young Adult author with a very successful series that I highly recommend. The books are Blue is for Nightmares, White is for Magic, Silver is for Secrets, and (in August) Red is for Remembrance.
Has anyone else read these? I read all three (and am waiting impatiently for Red) and I was amazed. I'm an avid reader of the YA-fantasy genre but these books blew me away. If you haven't read these... do so immediately!
