Friends or Fate. Fates & Mates, #4

Zell, a fierce and independent she-wolf shifter, has always felt the pull of destiny toward Drew, her brother's best friend. However, Drew's reluctance to embrace their bond-due to their age gap and his loyalty to her brother, Mica-drives a wedge between them. Fed up with his hesitation, Zell decides to take control of her destiny and embarks on a transformative sabbatical to Machu Picchu. In the mystical Andes mountains of Peru, Zell works with a wise guru who helps her harness her latent powers.
Under the guru's guidance, she taps into strengths she never knew she had. But complications arise when the guru's son, a charismatic Peruvian Jaguar shifter, becomes infatuated with her. As Zell grows stronger, she is torn between the allure of this new connection and her deep-rooted love for Drew. Meanwhile, in the Appalachian Mountains, Drew finds himself under suspicion as Mica investigates a series of brutal murders.
When he stumbles upon Zell and Drew's secret relationship, his discovery complicates an already tense situation. Zell rushes home, determined to clear Drew's name, but she quickly realizes that the danger is far greater than they anticipated. El, Zell's best friend, a witch, is in grave danger, caught in the crossfire of the same deadly plot that threatens them all. With danger lurking in the shadows of the Appalachian wilderness, Zell and Drew's love will be tested like never before, forcing them to choose between friendship and fate.
