He had just finished his first year of teaching second graders at Undermountain Elementary School in Sheffield and planned on celebrating his twenty-fifth birthday with his mother, Eliza, and his younger brother, Ashland but his plans and his life change when Daya kidnaps him. Daya Saban is an assassin with one weakness; her newborn daughter, Penchant. While Sean and Daya's relationship remains understandably rocky, Sean immediately forms a lasting bond with the baby girl that both puts Daya at ease and makes her a little jealous.
