Play of Passion: Psy-Changeling Series, Book 9

In his position as Tracker for the SnowDancer pack, Drew Kincaid must rein in rogue Changelings who've lost control of their animal halves - even if it means killing those who've gone too far. But nothing in his life has prepared him for the battle he must now wage - to win the heart of a woman who makes his body ignite... and who threatens to enslave his wolf.
