She didn't cross over to heaven after the death of her and her family as she wanted to stay with her big sister - Ever Bloom - who was neither dead or alive after the accident as she had become immortal.
Her mom and dad and her dog Buttercup were crossing the bridge but she didn't because a part of her longed to stay with her surviving sister.
Riley Bloom left her sister, Ever, in the world of the living and crossed the bridge into the afterlife - a place called Here, where time is always Now.
Riley and her dog, Buttercup, have been reunited with her parents and just settled into a nice, relaxing death when she's summoned before The Council.
She's been assigned a job, Soul Catcher, and a teacher, Bodhi, a curious boy whom she can't quite figure out.
Riley, Bodhi, and Buttercup return to earth for her first assignment, a Radiant Boy who's been haunting a castle in England for centuries.
