Tentative pick - I don't usually love true crime, but this looks at Lollie and Julie as people and as a couple, not just as murder victims. The author's recurring theme is how women and marginalized groups feel unsafe in the outdoors and she attempts to counteract that but also highlight very real concerns. It is a tricky balance.
I was more interested in the evidence and investigations (and their mismanagement) and found her approach not lurid.
