Series & Setting

Martini Club Background

I have to admit, I love a good series with a quirky group of friends. The Martini Club in The Summer Guests by Tess Gerritsen brings together retired CIA agents who have traded high-stakes missions for small-town life. These folks aren’t your average retirees. They meet for drinks, swap stories, and—of course—get tangled up in local mysteries.

I found myself wishing I could pull up a chair and listen in. Their friendship feels real, with inside jokes and gentle teasing. It’s not just about solving crimes. It’s about loyalty, second chances, and finding purpose after a career full of secrets.

The Martini Club members:
- Share a deep bond from their CIA days
- Bring unique skills to every situation
- Add humor and warmth to the story

Purity, Maine

Purity, Maine, sets the perfect stage for a thriller. I could almost smell the salty air and hear the gossip at the local diner. This town has two sides: the year-round locals and the wealthy summer visitors. That split creates tension you can feel on every page.

Some families have lived here for generations, working hard to keep things running when the tourists leave. Others just show up for the season, bringing money and sometimes trouble.

The mix of permanent residents and summer people means old grudges never really fade. A tragic accident from years ago still haunts the town. Secrets bubble under the surface, making every interaction feel loaded. I have to give props to Gerritsen for capturing that small-town drama. It made me want to keep reading, just to see what would happen next.

The Summer Guests by Tess Gerritsen: Plot

Missing Teen Mystery

I have to admit, I started reading The Summer Guests by Tess Gerritsen thinking I’d just do a few chapters before bed. That plan failed fast. The story kicks off with a missing teenage girl, and suddenly, I found myself glued to the pages.

The tension builds right away. The whole town of Purity, Maine, gets pulled into the search. I could feel the worry and fear in every scene.

The search for the missing teen feels real. People whisper at the diner. Neighbors peek out their windows.
The retired CIA crew can’t help but get involved. Their skills make the investigation sharper and more interesting.
The stakes get higher when a woman’s body turns up in the lake. Now, the mystery isn’t just about a missing girl. It’s about what happened years ago, too.

I kept thinking, “What if this happened in my own town?” The fear, the rumors, the secrets—everything felt so close to home. I couldn’t put it down.

Family Secrets

If you love thrillers with family drama, this book delivers. The Summer Guests by Tess Gerritsen doesn’t just focus on the missing girl. It digs deep into old secrets that families have tried to hide for decades. I saw how these secrets shaped the characters and the whole investigation.

There’s talk about a woman who vanished back in 1972. Her story mixes with the present-day mystery.
The family at the center of the plot hides things they never wanted anyone to know. Every new clue brings more questions about what really happened.
As the story unfolds, old grudges and hidden truths come out. I felt the suspense grow with every chapter.

I’ve read a lot of thrillers, and I know that family secrets often make the best stories. Books like My Sister, the Serial Killer and Middlesex use hidden truths to build suspense and drama. In The Summer Guests by Tess Gerritsen, these secrets drive the plot and keep the tension high. I found myself guessing and second-guessing every character’s motive.

To be fair, the way the secrets unravel made me gasp more than once. I love when a book surprises me like that.

Family secrets in thrillers add emotional depth and keep readers hooked.
Stories like The Fever and My Darling Girl show how hidden pasts can shake up families and entire communities.
In this book, the secrets don’t just affect one person—they ripple through the whole town.

I’ll be honest, the mix of a missing person and long-buried secrets gave the story a chilling edge. Every time I thought I had it figured out, another twist popped up. That’s what makes this book stand out for me.

Suspense & Pacing

Twists and Turns

I have to admit, this book threw me for a loop more than once. Every time I thought I had the mystery figured out, Tess Gerritsen dropped another clue or red herring that made me question everything. I love when a story keeps me guessing. My brain worked overtime trying to piece together the truth.

High stakes kept me glued to the pages. I felt the tension in my chest as the characters raced against time.
Foreshadowing worked its magic. I spotted hints early on, but they never gave away the big reveals.
Misdirection played a huge role. I followed false leads and got tricked by clever twists.

Research shows that twists work best when they surprise you but still make sense. This book nails that balance. I found myself flipping back to earlier chapters, looking for clues I missed. That’s the sign of a good thriller.

Maggie Bird and Friends

I have to admit, I got way too attached to Maggie Bird and her crew. Maggie stands out as the heart of the story. She’s sharp, funny, and always ready to jump in when things get tough. I loved how she never lets her age slow her down. Her friends from the Martini Club bring their own quirks and skills. Each one feels real, not just a sidekick.

The Martini Club: These friends tease each other, but you can tell they’d do anything to help. Their banter made me smile, even during tense scenes.

I found myself wishing I could join their club, even if just for one night. The way they support each other gave the story warmth.

Police Chief Jo Thibodeau

Jo Thibodeau surprised me. She’s not your typical small-town cop. She’s smart, tough, and cares about her community. I liked how she handled the pressure when the town started to panic. She didn’t always have the answers, but she kept pushing for the truth.

Jo’s strengths: She listens, asks good questions, and doesn’t back down.
Her flaws: Sometimes she doubts herself. That made her feel more human to me.
Relationship with Maggie: They don’t always agree, but they respect each other. Their teamwork kept the story moving.

I’ll be honest, Jo’s scenes added a lot of tension. She made me root for her, even when things got messy. The mix of old spies and a determined police chief made this book stand out from other thrillers I’ve read.

Gossip: Secrets don’t stay hidden for long. One person talks, and suddenly the whole town knows.
