Wow, there is a lot here that I'm not comfortable with (and no, homosexuality isn't on that list). The violence between Silvio and Stefano is explicit in their first sexual contact, and later events make it pretty clear that Silvio's long-term relationship has not only violence but hints of child abuse woven into it's DNA. Silvio's dismissive "it's not pedophilia" wasn't enough to make his experiences any less difficult to stomach.
With so many sections to the story, I'm not tempted to spend another $3 to get the next volume. Despite the potency of Volume 1, this is too dark for my tastes.
