Infatuation (A Mystic Series Story) - Brietta & Kegan, #1

Brietta was like a sister to him. Nothing more. Ever. Until she grew up. Fifteen-year-old Kegan Adair has known Brietta Gilmore since she was born. He's taught her tricks, caught her falls and watched her grow, but he's never seen her like this. The girl he's always loved like a sister suddenly disrupts his pulse, catches his breath, and wreaks havoc on his teenage hormones. He wants her, but exposing his feelings for her would risk more than a broken heart.
Taking that leap could jeapordize his reputation with her coven, ruin his relationship with his best friend, and destroy his happily ever after.
