About This is Not a Test: The Definitive Edition with Please Remain Calm

It’s the end of the world. Six students have taken cover in Cortege High, but shelter is little comfort when the dead outside won’t stop pounding on the doors. One bite is all it takes to kill a person and bring them back as a monstrous version of their former self.

To Sloane Price, that doesn’t sound so bad. Six months ago, her world collapsed, and since then, she’s failed to find a reason to keep going. Now seems like the perfect time to give up. As Sloane eagerly waits for the barricades to fall, she’s forced to witness the apocalypse through the eyes of five people who actually want to live.

But as the days crawl by, the motivations for survival change in startling ways, and soon the group’s fate is determined less and less by what’s happening outside and more and more by the unpredictable and violent bids for life—and death—inside.

When everything is gone, what do you hold on to?

My Review

This is Not a Test is one of the only Courtney Summers novels I hadn’t yet read. (The only one I still haven’t gotten to at this point is Fall for Anything.) This version includes both This is Not a Test and Please Remain Calm, a novella from the love interest’s perspective that takes place after This is Not a Test.

This book was so intense that I literally read it in one session. The threat of zombies is everpresent, but that’s not the only threat the characters face. The tension between members of the survivors Sloane hides with just keeps going up. One group blames a person for the deaths of others. The group disagrees on how to treat a new survivor discovered within the compound. Sloane herself begins the story intending to end her life, so she is a danger to herself for quite a stretch of the narrative.

Throughout the story, Sloane thinks about her missing sister and her father, who abused her. I had a theory about where that thread of the story was going, but I was wrong. I do appreciate that the author wraps up the unanswered questions there in a way that allows Sloane to move on. I also like that she finds a connection to Rhys, a boy from the group of survivors she was with in the school.

As you’d expect from a Courtney Summers novel, this story is sharp, smart, and deeply moving. I don’t even know if I blinked through some of the chapters. I didn’t want to miss a single second.

If you’re looking for a zombie story packed with social commentary and exploring the connection between sisters and girl friends, definitely do not miss this one.
