7 parts Complete Isidra yearns to become one of the Andarae, a global peacekeeping force of mortals and dragons. Syl has a grudge against the Andarae because they betrayed her family.
When the Sanctuary of the Andarae is attacked, a magical accident binds Isidra to Syl. Irreversibly connected by blood and soul, they're forced to team up as a dragon-rider pair and train together. That would be bad enough, since they can't stand each other...then bloodless corpses start turning up, and it becomes clear that someone's hellbent on destroying the Andarae from within.
With the future of both their races at stake, Isidra and Syl must put aside their differences to solve the string of violent crimes. But that puts a target on their backs, which means the next bloodless corpses might be them. They'll have to stay one step ahead on this magical murder mystery...
Because if they can't learn to work together, they'll die together.
