When Harry Potter's Hogwarts letter raises red flags for Severus Snape, he delivers the letter instead of letting Dumbledore handle it. Severus does not see a miniature James Potter when he encounters the scrawny child, drowning in clothes that don't fit and holding himself carefully away from his aunt like she might strike him at any moment. Severus is reminded only of himself.
Severus's choice to rescue Harry might damn him when Voldemort returns, or it might change everything.
The start was good, and some scenes in between, but I very much did not like the way how most of the action was only summarised, much from Snape’s PoV. The sudden turn into smut in chapter 31 was, indeed, warned about at the beginning, but still, ugh.
Overall an okay story (even if tedious to read). But then, the author’s become the first to block me on AO3… over a spelling correction suggestion. I’ve written much harsher things without getting that, so… snowflake much? As a spare-time author of published-on-the-internet-for-free things myself (and a huge lot of them), I do invite those myself, even got one from a piece of software last week or so and took the time to fix it in all files, not just the one pointed out. But noooo…
