The Edge of Over There (The Day the Angels Fell #2)
by Shawn Smucker
Description from Goodreads
Before the Tree of Life, everything in Abra Miller's life had been predictable. But after the Tree and the lightning and the angels, everything felt tenuous, like holding a soap bubble in the palm of her hand. She spent years looking for signs of that other world, waiting for it to break through. When it didn't, her friendship with Sam Chambers grew cold and distant, and they both wondered how any of it could actually have happened.
Four years later, 16-year-old Abra's long-delayed quest to find the next manifestation of the Tree of Life is renewed when she sees a woman walking up the road--a woman who looks exactly like Sam's dead mother. The woman directs her to New Orleans where she will find the grave of Marie Laveau, one of seven gateways between this world and Over There. As Abra enters The Edge of Over There and begins her pursuit of the Tree once more, she doesn't know whom to fear or whom to trust. But she's starting to think that some doorways should never be opened
