Book That Wouldn't Burn

I really enjoyed the story of Livira and Evar, and I especially loved learning more and more about the mysterious library. I found their romance to be emotional and relatable, especially for a straight couple. Unfortunately I feel like the ending didn't quite conclude as much as it just stopped, but I presume it will be picked up again in the next book, for which I await with bated breath. The fact that this book relies heavily on time travel and that I actually LIKED it should be a huge testament to it's strength.
