Marked by the Alpha's Secret Sacrifice

Aubrey always thought her childhood best friend, Derek, would choose her as his mate—until she overhears him call her 'easy' and cast her aside for the prom queen. Heartbroken, she discovers Derek’s cold, powerful brother, Caleb, secretly saved her life years ago by binding their fates in a forbidden werewolf ritual. Now, as Caleb lies dying and only her kiss can save him, Aubrey must decide: repay her debt and risk her heart, or stay loyal to a boy who never truly valued her.
