I like the nod to early novels with the false author who introduces their found evidence/epistolary story. The buildup is very effective and the incidents with her brother in particular made me not want to read it before bed. The ending makes very little sense given what we have to go on as readers. I get that she's an unreliable narrator but this is taking it too far and using that as a cheat to force a twist in the story, IMO. However, I see that this is #1, so perhaps #2 will redeem that for me.
