📖 Genre: Young Adult • Mystery • Fantasy
🌲 Setting Vibe:
Enchanted gothic estate in the Hamptons
📜 Synopsis:
Mullory’s mom disappeared, leaving her only with a warning to “Run if the strange finds you.” Now, Mullory is trying to take care of her sick grandmother, keep the bills paid, and attend school. Obviously this is basically impossible. So when letters begin to appear in weird places, like the fridge, she eventually caves and reads one. She’s been invited to attend the estate of a deceased billionaire and participate in a game to determine who wins his inheritance. Cue several days of spectacularly fancy parties, all sorts of magic, illusory and otherwise, and a murder mystery, and you’ve got the rest of the idea.
👤 Main Characters:
Mullory • Lyric • Ellison • Xavier • Mateo
The book is divided into chapters with first-person narration for each of them. Mullory, Lyric, and Ellison have the most individual chapters. Cavalancia’s characterization was superb. These are fully fleshed young adult characters with flaws, virtues, dreams, and fears. Even some of the minor characters were more well-rounded than one was initially led to believe.
💜 What I Loved:
- The setting was perfect. Total Agatha Christie Hercule Poirot dinner party vibes. I loved how huge the estate is, with all of its different rooms, and how utterly eclectic the style.
- The mystery itself. I did solve the primary question early on, but uncovering all of the other aspects needed to reach that conclusion was delightful. Having such a large cast of major and minor characters to suspect made it even better.
- The magic and illusions at the parties were such fun. I could easily picture myself there.
- The characterization, as mentioned above, is the best part.
⚖️ Themes:
- Identity and self-discovery — Mullory’s central question seems to be “Why me?” She’s been surviving rather than truly understanding herself, and this mystery seems to be tied to her and her mother’s past.
- Family secrets & legacy — The Stoutmire family has been built on generations of hidden truths, resentments, expectations, and inherited burdens. Everyone seems to be carrying pieces of the past.
- Wealth, power & privilege — A game designed to determine who inherits a vast fortune and access to magic naturally invites questions about what people will do for power, who deserves to hold it, and how wealth shapes relationships.
- Appearance vs. reality — This is a huge part of the story. Nearly every character has secrets, hidden motives, or carefully crafted personas. The magical illusions reinforce this.
- Trust — The synopsis practically frames the book around deciding who to trust. Mullory must navigate alliances while knowing everyone may be withholding something.
- Truth & perception — The story explores how incomplete information shapes understanding. Then add illusion magic.
- Belonging — Mullory starts as an outsider. Lyric has always felt like an outsider. The story explores what “family” really means.
- Choice vs. inheritance — The Stoutmires are defined by what they’ve inherited. Mullory may ultimately be defined by the choices she makes rather than the legacy she’s handed.
⏳ Pacing:
The pacing was ideal. It wasn’t so slow I got bored, and it wasn’t so fast I got confused. It was genuinely fun waiting to see what magical thing would happen next.
✍️ Writing Style:
Cavalancia’s writing is accessible and highly readable. It’s vivid without becoming overly descriptive. It’s dialogue-driven and character-focused. Setting descriptions, especially at the parties, are playful and imaginative with their use of magic and mystery. It’s absolutely dripping with red herrings, secrets, and misdirection, and somehow manages to remain emotionally grounded despite all the fantastical elements.
📚 Recommendation:
This is perfect for young adult readers. Everyone parents differently, so it’s difficult to recommend an exact age group, but I personally would’ve been comfortable allowing my own child to read this from around fourteen years old and up.
The publisher’s synopsis likens it to The Inheritance Games and Hotel Magnifique. Adults who enjoy Agatha Christie’s Hercule Poirot mysteries might also find this to their liking.
As a YA novel, this is a four-nerd read for me. As an adult reader, some elements felt a little younger, which lowered my personal enjoyment slightly.
