Timeless is the final part of the Transcend Time Saga, and will be released on November 20, 2012.
I love the cover! It was designed by Michelle Madow herself.
I haven't started reading the series yet but I heard it was good and it's in my to-reads list for quite sometime now. Hopefully I'll have a copy of it soon!
