I couldn't do it.
Got about 100 pages in, but NOTHING was happening. Oh, the MC was making lists, but... It felt like she jumped at a chance to dump her boyfriend, then never gave him a chance to talk to her about it. Not gonna lie, it sounds like he was a cheating jerk.
But that doesn't mean he was. And her actions are suspect on how she found out about it. I mean, so you see something online. Jumping to conclusions isn't the way to go.
And following that up with 'I'm dropping the modern world' seems like a bad idea. Worse, she forces someone else to do it too.
So, I've returned the book and am moving on to the next. Let ya know how that goes.
