Mated to the Alpha Knight

Celeste Williamson is about to turn eighteen, which means she's about to find her mate - this is fine and all, but what happens when her mate turns out to be her brother? Will she accept him or find out a hidden truth? Be his mate or reject him to keep her own sanity? Not only is her brother her mate, but talk of a prophecy starts to cloud her judgement... And even worse, Celeste seems to be the target... How will she balance these challenges? Will she find out her entire life has been a lie? Or will she find her destiny within these hidden truths?
