Where's my mate

Finding a mate should be easy, yeah? But for Chase, he thought she didn't exist.
Being an Alpha's eldest son, meant, technically he should of found her by the age 22. Coming into his 26th year, made him a lot older and the talk of all the surrounding packs. Will he find her by his 27th birthday or will his throne be passed on to his soft hearted baby brother and potentially be the death of the Black Rose pack.
