**Warning: This review may contain spoilers for book one; "Darkhaven" reviewed here.**
In this sequel to "Darkhaven," Ayla Nightshade is adjusting to being the new overlord of Mirrorvale, and being able to freely transform into her changer self; a fire-winged alicorn. She also has settled into her relationship with Tomas Caraway; the infamous Breakblade who is now a hero for saving Ayla's life in the first book. The conflict here is an assassin has been sent to kill Ayla and the secret that pistols can harm changers has managed to leak from the walls of Mirrorvale. Since Tomas is currently accepting new recruits into the Helm, the assassin could be among them.
Like the first book, this story revolves around the hunt for the true identity of a killer. Despite the repeated theme, the tension, character development, and pacing are well worth the read. In this second installment, we learn more about the cities surrounding Mirrorvale, the nature of changers, and the impact of guns being introduced into a fantastical, steampunkish (because there's airships and airships = steampunk, apparently). In addition, many books in a series get sappy and annoying when the romantic interests finally pair off but not here. The relationship between Ayla and Tomas is there but it doesn't take over or drag down the plot. It was refreshing to see the couple still retain their individuality, face conflict in their relationship, yet still remain a united force.
When the assassin is revealed and everything is wrapped up, it feels satisfying for the journey is took to get there. Each character's weaknesses and strengths are faced with grace in a well-built fantasy world and the concepts brought forth - such as the use of alchemy - leave the potential for interesting story avenues in the future. If there is a third novel in this series; I look forward to reading it.
If you like detailed world-building, fantasy creatures, and intriguing assassination plots, you will enjoy this book.
