Content warnings: death, murder, grief, paranormal activity, spirituality, age gap, gore
Summary: Sage is an ordinary girl-except for the fact that she’s a werewolf. Struggling to find her place, she bounces between the supernatural and human realms. But everything changes when her best friend, Lucy, is found dead in the human world.
Determined to uncover the truth, Sage joins the investigation led by the brooding and infuriating warlock, Oren Rinallis. Despite lacking magical powers or immortality, Sage has a unique gift — her ability to track down a killer like no one else.
But as Sage and Oren clash at every turn, they must learn to work together — or risk letting the killer slip away forever.
ALL THE HIDDEN MONSTERS is a gripping blend of humor, suspense, and supernatural intrigue, featuring a cast of characters you won’t be able to forget. With unexpected twists and heart-pounding moments, this thriller will keep you guessing until the very end. Perfect for fans of dark mysteries, supernatural suspense, and enemies-to-lovers!
A Howling Good Setup
The story follows Sage, an 18-year-old werewolf grappling with survivor’s guilt after losing her family in the attack that turned her. When her closest friend Lucy is found murdered in the Upside (the human world), Sage teams up with Oren, a grumpy warlock detective with a dangerous past. Their mission? To uncover the truth behind Lucy’s death while navigating a growing list of werewolf murders. Sage’s determination to join the Arcanum (the supernatural police force) adds stakes to an already intense investigation!
What Makes It Shine
Jordan’s world-building is top-notch. The Downside feels alive—a hidden underground society where supernatural beings coexist in a functioning community. The contrast between the Downside and the human Upside adds depth to the story’s setting. Sage and Oren’s dynamic is another highlight; their reluctant partnership evolves into mutual respect, peppered with witty banter. While hints of romance exist, Jordan wisely keeps it subtle, focusing instead on their teamwork.
The supporting cast is equally memorable. P, Sage’s poltergeist roommate, steals scenes with her humor and loyalty, while Berion’s flamboyant fashion sense adds levity to darker moments. The found-family trope is beautifully explored as Sage builds her own “pack” amidst tragedy.
For Shadowhunters Fans
If you’re a fan of the Shadowhunters series, All the Hidden Monsters offers a similar blend of supernatural intrigue and mystery. Like the Shadowhunters universe, Jordan’s world is rich with magical creatures and hidden societies. The dynamic between Sage and Oren echoes the partnerships found in Shadowhunters, where humans and supernatural beings work together to solve mysteries and fight evil. The blend of action, humor, and emotional depth will resonate with fans of Cassandra Clare’s series.
Twists And Turns
The murder mystery is tightly woven, keeping readers guessing until the very end. Just when you think you’ve figured it out—bam! A twist throws you off course. The pacing is brisk but never rushed, making it impossible to put down!
Room For Growth
While All the Hidden Monsters excels in many areas, some may find Oren’s age gap with Sage unsettling. Thankfully, their relationship remains platonic here. Also, a few minor characters could have used more development given their eventual importance to the plot.
Verdict
This debut novel is a breath of fresh air in the YA fantasy genre. With its compelling characters, immersive world-building, and a mystery that keeps you hooked, All the Hidden Monsters sets a high bar for its upcoming sequels. Whether you’re here for the supernatural intrigue or the emotional depth, this book delivers on all fronts.
