This may be just due to my attention span being low, but I found this story structure really difficult to read and thus, didn't find it all that hot. Just my opinion
The blithe assumption that each of the four protagonists would jump into such an arrangement was a stretch; perhaps they all knew each other so well that it made sense--but a reader didn't have that much background information (or at least I didn't) to make it a no-brainer.
But I loved the simplicity of the concept!
