Love’s Warrior by Jennifer Hilt

All’s fair in love and the war to win back his fated mate…
Being the daughter of Aries, the God of War, means Jessica Tindal is an Amazon warrior. But she’s given up her bloodthirsty ways to hideout working as an herbal healing witch. Too bad she’s stuck in an Arctic ice station with a killer intent on framing her.
Enter Paranormal Marshall Carson Slater—ice bear shifter, silver-haired hottie, and oh yeah, Jessica’s ex-husband. Carson arrives in Icy Cap determined to do two things: take down the ice station killer and reclaim his wife. His protective instincts drive him to keep her by his side at all times, which plays perfectly into his plan to seduce her back into his bed and his life. Now all he has to do is prove her innocence and win her heart before the real killer strikes again.
