[Rating the first published volume for the whole series]

The early chapters are the best, but when the whole crime-mystery + past-life-mystery really got the center stage, I felt like the early feeling and overall vibe I enjoyed went away.
It's like the concept was so good, yet it got overly complicated.
As a whole, I think I've preferred "A Good Day to Be a Dog", including the conflicts and struggles of the later acts.
