Alexandra Adornetto writes young adult fantasy and romance, best known for the Halo trilogy. Halo follows angel Bethany Church after she is sent to Earth with Gabriel and Ivy to protect a small town from growing supernatural darkness. Bethany's relationship with human student Xavier Woods becomes central, creating tension between her mission and the rules governing angels. Hades and Heaven continue through demonic threat, separation and the consequences of crossing supernatural boundaries. Adornetto's books are accessible, romantic and faith-inflected rather than horror-driven, fitting YA angel fiction, paranormal romance and supernatural series where a central love story carries much of the plot. Halo is the defining entry point for the trilogy. Halo is the required starting point because Bethany and Xavier's relationship, the angelic rules and the conflict between heavenly duty and earthly attachment continue directly through Hades and Heaven.
