One star might be harsh, but I have to do it because I stopped reading this halfway through, felt relieved to be done with it and then somehow went back to it, and wish I'd not ended up finishing it. The infuriating thing is that any individual chunk of this is likely not bad, and some of them are pretty good, but the whole is just not there. (And the editing .. well, it's a modern 700 page novel, with dangling plot threads, so no, there was no editing.)

If it had a "warning: fixup novel" in the front matter, I'd give it 2 stars. But it's a stealth fixup, not done well. Be warned.
