When Worlds Collide Series by Kelly Apple

When she bought her new house, Char James didn't plan to also take on a ghost. It’s rude, creepy, and a downright terrible roommate. Despite that, she’s determined to show it they can live in harmony. Hopefully. But Char's entire perspective changes when a surprise encounter rocks her world. She learns that sometimes pranks can be helpful, sometimes a ghost isn’t really a ghost... And sometimes the scariest creature of all is the most protective.
