What's the Name of That Book??? discussion

A girl that died on a bridge and doesn’t remember anything about herself or her past life meets a teen guy that can see her. They obviously fall in love. I think he almost drowns at one point. She eventually figured out who she was and I believe her name was Amelia. I think his name might have been Ben. Seeing spirits runs in his family. I know his grandma didn’t like her coming around. I remember that she followed him on a family vacation where his cousins might have had ghost friends too. I know they had to save the local teens from bad spirits trying to kill them on a bridge. The bad spirits would possess the teens and try to make them kill themselves or each other.

Please help I’ve been trying to remember for over a year. I might be able to provide a few more details if needed.

From the Kirkus Review:
- "Amelia knows she’s dead and that she drowned, but little more.
Then she encounters a drowning boy, Josh, and though he survives, his brief experience of death allows him to see her. Soon they’re an item—his presence and touch reawaken her senses. Josh takes her to school, and together they investigate her origins..."
