Reeling from Cassiel's confession, Dyna struggles to understand what the Blood Bond means for them both, all the while trying to stay one step ahead of a newfound enemy. When reuniting with a familiar sorceress, she realizes the only way to defeat Tarn is to find her Guardians-all of them.

Cassiel never meant to tie himself to a human, especially one that inexplicably draws him. But then the bond develops a startling change, and it puts into question everything he thought he knew.

Zev straddles the line between human and wolf, unsure if his dark thoughts truly belong to the Madness. It's growing stronger, determined to take over-and he may just let it.

The journey to get the answers they each need will test them all. But what Dyna doesn't know is that it comes with a price, and it may cost more than she bargained for.
