Havoc

For the first time in his life, Rain Ryland belongs. He's found a home with the wolf shifters of New Wurzburg and is no-holds-barred in love with Friederike Burkhart, their soon-to-be alpha. But the ascension to power is never easy for a new alpha, and challengers will come from an unlikely source—and bring into jeopardy not just Freddie's position as alpha but her blooming relationship with Rain.
Rain has never shied away from a challenge—or a fight. And he's ready to fight like hell for the woman he loves. But then a vision shows him that the biggest challenge of all to Freddie isn't to her alpha status but against her life...and he's the one who delivers the killing blow.
The Haven series is best enjoyed in order.
