2.5* but I rounded up.
Like most any piece of writing, Paper Walls has its strengths and its weaknesses.
The strength that carried me through all 25 "chapters" lay in the natural talent of the author. He has a nice way with words and that is not something that can be said for everyone. Paper Walls is an easy read that is mostly enjoyable. It's the type of work one looks for when home sick-- something that can help an otherwise gloom mood, and by being mostly light and airy, it doesn't get too mired in the darker aspects of the human psyche.
The weaknesses, though, are plentiful and apparent. The greatest being the desultory or unmoored story, itself. Having read the whole work, I am still unsure what the tale was really about. Timelines were arbitrary, characters were mercurial and capricious, and facts established were not rooted in terra firma. The story appears to have been developed on the fly with no forethought by the author of the story that he wished to convey or how it would end. Characters appear toward the end that have no real connection to the preceding work and barely alter the course of ending while previously important characters vanish in the middle under the most reasonable explanation of ANY of the characters throughout the story. The inordinate tragedies affecting this group of teenagers would be overwhelming, but luckily, the author chooses to not dwell of the horrific events that have affected them-- but that only begs the question as to why one would then include them since they play very little if any role in the story except to minimally cause "drama"?
The writer had some nice characters and had he worked through the details and storyline with a thoughtful eye and ear toward editing really delivered it into the end zone, but sadly, the story becomes lost and his attempt at a 'Hail Mary' fails to deliver.
I suspect that Paper Walls is the first attempt by the author of such an undertaking. He should be commended for his effort. I suspect, if he focuses, his future works will hit the mark. He has ability.
