About They Bloom at Night
The author of the New York Times bestselling horror phenomenon She Is a Haunting is back with a novel about the monsters that swim beneath us . . . and live within us.
Since the hurricane, the town of Mercy, Louisiana has been overtaken by a strange red algae bloom. Noon and her mother have carved out a life in the wreckage, trawling for the mutated wildlife that lurks in the water and trading it to the corrupt harbormaster. When she’s focused on survival, Noon doesn’t have to cope with what happened to her at the Cove or the monster itching at her skin.
Mercy has never been a safe place, but it’s getting worse. People are disappearing, and the only clues as to why are whispers of underwater shadows and warnings to never answer the knocks at night. When the harbormaster demands she capture the creature that’s been drowning residents, Noon finds a reluctant ally in his daughter Covey. And as the next storm approaches, the two set off to find what’s haunting Mercy. After all, Noon is no stranger to monsters . . .
My Review
I heard so many incredible things about Tran’s debut that I’ve been eagerly anticipating reading their books. I still need to read She is a Haunting, but after reading They Bloom at Night, I seriously cannot wait. Just wow.
The balance between the elements of this book– its characters, the setting, and the tension in the horrific elements is absolutely perfect. The mostly abandoned town of Mercy feels incredibly real. It was so easy to picture where things happened and feel completely immersed in the landscape of this story. Noon is also a fabulous main character. Her relationships with others are so layered. She loves her mom but feels trapped by their life and grief over her brother and dad’s deaths. She reconnects with an estranged friend and has mixed feelings about that, too. When circumstances force her into a reluctant alliance with a girl, Noon is surprised by the relationship the two forge.
I loved the themes in this book about identity, specifically about being more than one thing that happened to you. I loved the message about having a found family or community to protect you and help you face uncomfortable truths. One line in particular says it well: “Sometimes we need people to hunt the things inside of us that need to die but that we aren’t ready to kill.”
They Bloom at Night is a tightly plotted story that doesn’t waste a single word. This would be a perfect (or terrifying) book to read during a hurricane or big storm. Fans of The Shadow Sister by Lily Meade or Don’t Let the Forest In by C. G. Drews will not want to miss this one.
