I'd suggest checking manga forums or dedicated Bleach fan sites. They often have detailed breakdowns and recommendations on where to pick up after a specific part. Sometimes, the author or official sources might provide cues as well.
I don't know who the author of 'the precipice a novel' is. There are so many novels out there, and without more context or research, it's impossible to determine the author.
I'm not sure specifically as I haven't read it. It could be about a literal precipice, like a dangerous cliff, and perhaps the characters' experiences related to it, such as facing danger or making crucial decisions on the edge of this precipice.
Honestly, I don't know when the TYBW manga starts. But you could search manga databases or ask in manga enthusiast communities to get the details you need.
