Really enjoy this book as Cade is one of my favorite characters in the IAD series. Holly, as a computer-code writing Ph.D. student with OCD--who becomes a Valkyrie--was unexpected and enjoyable too. Loved the two of them together. The quest for the sword and what Cade will do to get it were suspenseful and surprising. Despite a lot of tension between the characters, there were also sweet moments between them that helped to show how they built a connection in the middle of this road-trip book. Great combination of verra sexy and butt-kicking. Also a nice set-up to Kiss of a Demon King (Rydstrom & Sabine's book), although I read this in reverse order.
