My predictions:
Spoiler:
It seems to me that Malia Gedde is the real Voodoo queen or whatever... the story of Laveau implied she was just a figurehead for the real powerplayer. Malia has some sort of voodoo thing going on with Gabe. Now that I've received Wolfgang's journal with the "shockingly" similar plotline in his family's past, I'd now put a hefty wager on it. I imagine the game's remaining major plot points will mirror those in the journal's last page.
Probably missing a lot of details
I'm on Day 5 now and stuck on some nasty puzzles
