We didn't formally review Ember on the blog though I really loved it.
We did a feature post where we "dared" our reader to read the series:

This week, I decided to dare you to read Firelight by Kristen Callihan because I just added the third book, Winterblaze, to my kindle (from netGalley) so I thought you should all catch up on this must read series!

Firelight is a breathtaking gothic twist of The Beauty and The Beast’s story. There are many retell out there, but this one is subtle and I truly enjoyed it! Callihan’s writing is simply fabulous, infusing credibility to this historic setup. Written in old English style and respecting the old traditions and morals, Firelight shines by its authenticity and I loved every second of my reading experience.

If you love to historical romance with a paranormal twist, Firelight is the perfect novel for you!

A short intro to the first book, Firelight, detailing the backstory of the main characters. While interesting if read in conjunction with Firelight, I don't know that this is enough to entice a reader to go on with the series.

Great little scene of Miranda and her family. Usually, short novellas don't serve a purpose but this one DOES! It is a prequel, so it is before Firelight. I throughly enjoyed it because it made me want to go and do a re-read of Firelight, that's how great it was!
