Soul of a Lynx by Lacey Thorn

Captured…
Murphy’s life has become nothing more than a series of beatings that leave him hovering closer and closer to death. His lynx is locked inside him. His bond with his brother gone. No one is coming to save him, and he no longer believes he can save himself.

Unwanted…
Oakley Talbot is nothing more than a science project, created in a lab by a mad scientist. Shifters hate her for the blood running through her veins. Hunters hate her for the exact same reason. She belongs nowhere. Not with the family she has. Not with the team she’s built.

Soul Bound…
A man unwilling to die. A woman with no idea how to live. Together, they’ll find more than either hoped for and bring the mightiest hunter of all to his knees.

While each novel is a stand-alone regarding the HEA of the couple, the plot develops with each story. This series is best read in order.
