“Last Summer at Camp” is a photobook which tells the story of Philmont Scout Ranch and its backcountry staff: from being a participant on a 12-day trek and discovering the Ranch’s enchanted landscape, to working a first summer in the backcountry and finding a deeper connection to others and oneself, from July 4th and the rodeo to leadership softball—a complete scatter-to-gather album from Kernes’s decade-long experience.

In this tearful conclusion to the series, Dr. Steve announces that the government has forced him to sell the campgrounds to the state. The girls are heartbroken, until they decide to take a stand. They gather a group and head to the state capital to protest on the camp's behalf, replete with signs, chants, and plenty of determination. Will the girls plan work, or will this be the last summer they're all together?

Who I Killed at Camp Last Summer takes a first-person approach to the slasher genre, entirely from the killer’s perspective. It centers on a pair of horror-fanatic siblings, Ashley and Alex Byer, who attend a two-week summer camp with their school. The outlook of their adventure turns grim, however, when campers start dying in supposed accidents. The deaths are reminiscent of a previous camp, which got decimated by another killer some twenty years before. Soon many campers die, and no one is safe, as an old evil seems to have returned. This unique tale plays with the typical horror summer camp tropes and uses them in new and fun ways, while also touching on difficult human issues such as depression, identity, and the struggle of belonging, in a way no reader will ever forget.

Amid the usual excitement and turmoil at summer's end, Dr. Steve announces that Camp Lakeview will soon close permanently, and while each camper reacts differently to the news, ultimately all come together and make the most of their remaining time.
