Sailing With Her Wolf. The Nightstar Shifters, #1

Wolf shifter, Marley Gerwulf, was protective of her human best friend, Zara York. Their friendship dated back to their sophomore year in high school. Throughout the years they had been glued to each other's hip, experiencing life together. When Zara broke up with her longtime boyfriend, Marley suggested a three-week girls trip, sailing the Pacific Ocean. It would help her friend clear her mind and celebrate her newly found single life.  Marley had spent the last fourteen years of her life, knowing they'd only ever be friends.
Her wolf had identified Zara as her mate the day they'd met. The urge to mate was strong, but she was always able to overcome it, knowing she'd rather have Zara in her life as a friend, then not at all.  After setting sail with Tahiti as their destination, an intense storm caught them off guard damaging their yacht. Floating aimlessly along in the ocean, Marley was determined to ensure their survival.
With life or death situations at every turn, will Marley be able to protect Zara while resisting the call to mate?
