Star is a felimorph: a cat-shifter bonded to a witch as her familiar. She leads a miserable life bound to an old hag who abuses Star's weak magic.
One night, she bumps into Bircher, a felimorph who claims to have no bond. He offers to help free Star so she can join his tribe, but she's unsure her limited strength can overcome the bond forged at birth.
When Bircher realises Star's magic has been stolen, they embark on a journey to recover her lost powers from the witch intent on keeping them for herself.
From witches to warlocks, to sorcerers and their vampiric familiars, the aluka, Star's journey to awakening is only the beginning.
In the epic conclusion to the Devil's Deal series, Freya has one final chance to discover the full potential of her own power, and to use it to restore balance in the universe - once and for all.
