Ravensgaard Heir by Melle Amade

Her family was slaughtered, she is quite sure her fated mate helped.

Davin has lived on the outskirts of shifter society her whole life. A soldier among soldiers she has battled the Hunters until her cell is wiped out by a devastating hit.
Called back to Castle Brannach she is thrown into the center of the Ravensgaard court, only to discover she is fated to marry the Lord’s strikingly handsome son, Riordan. But the longer she stays at the Lord’s castle, the more she realizes his self-righteousness and entitlement are weaving destruction against their own people.
As Davin uncovers the profound deceit of the Lord’s rule, she vows to overthrow him; but first, she must win over the aloof, brutal, and alluring Riordan to revolt against his own father and save their people.
