Didn't realize this was part of a series missed the first one,Was a little confused how everything develops but in all it is a very good story.
It has good characters in Bone and Xander and all the rest that helps the story along.
Bone and Xander are hiding things that about themselves that prevent them from becoming who they could be.
As thing develops they come to some understanding about themselves.

Xander, former cad about town, and current demon hunter, is trying to stem the tide in the Apocalypse by giving the humans a fighting chance against the demons. But when he is wounded in battle he is healed by weapons maker, tinkerer and former Seraph, Bone.

Bone is determined to remain neutral in her dealings with demons, hunters and humans. She wants them to have a fighting chance rather than one side having a clear advantage. She wants to atone for what she sees as her descent into darkness and her dalliance with Rook, demon and all around d%&k!

Rook has requested a very...particular instrument be created. Bone knows that it is to keep large numbers of humans obedient, she just doesn't know how yet. But can she avoid her intense feelings towards Xander long enough to figure it out?

Dommiel, Anya, George & Kat and the very easy to like demon band members inc Axel are back to entertain, amaze and be all badass! Throw in a cute as a cherub Nephilim child and Bone is about to find out that she may not be as neutral as thought.

Bone may be trying to paint her heart the blackest black but its shiny angelic beginnings keeps coming through.

"Hardest Fall" is a paranormal romance about Bone and Xander. Bone is a demon who was formerly a Seraph who fell from grace. She now forges powerful weapons in the apocalypse for all sides- she is neutral in the waging war between humans and demons. The book begins with a bang, when Xander is brought to her on the brink of death to be healed. He is a demon hunter, but Bone still feels a pull to him and her song responds, healing him.

Once he is healed and wakes up in her bed (alone), Xander witnesses some of the demons ruling London, Rook and his brother, have asked her to forge a special crown, which could allow them to control the wearer. Determined to maintain her neutrality, Bone is considering her options. Xander attempts to get her on his and humanity's side, pointing out that such a weapon would not be part of her neutral pact.

As Xander and Bone work together and with the other hunters to figure out what Rook is up to, they also learn more about each other and a romance grows. While I found the story intriguing and enjoyed the main plot, I did feel like I was missing some big pieces of the world building. Notably, I did not read the first book, so I am assuming readers learned more about this apocalyptic world in that book. I would have liked a recap in this book regardless. We also know both Bone and Xander have a heavy past, but it takes a long time for the reveal, and by then, it almost seemed late, as it was harder to care, because of all they are doing in the present. I would have personally liked more information earlier in the story.

In terms of the romance, this was pretty strong with an immediate connection but slower to physical action (though not too slow). The connection is built with several conversations and reveals. The overall story was really fascinating, and I would have enjoyed more time learning about this new world and the demons who run it as well as the powers of these varied creatures. I assume this will keep coming out through future books in the series, and I would definitely be interested in reading more.

Overall, it's a solid paranormal romance, and I will be curious to see how this series evolves over time. Please note that I received an ARC from the publisher through netgalley. All opinions are my own.
