Genre: Mystery & Suspense / Romance
Will the key unlock more than a vault filled with treasure?
Brooke Sumner has been carefully avoiding Storm Whitlock ever since he betrayed her trust. When he joins Caspar’s mysterious treasure-hunting group, she steps away to focus on her antique shop and keep herself busy.
Then Caspar invites her back for one final assignment, and Brooke is torn. Returning to Halstead Manor to help the team find the second half of a key is intriguing. It also means she’d be working with Storm. But she doesn’t trust his motives, so she reluctantly rejoins to keep him in check.
As they dive into their expedition, Brooke finds her heart softening toward those she’d once held at arm’s length. And is it possible she misunderstood Storm’s betrayal of their friendship?
“In this friends-to-more romance, we get to see the beauty of being known, being loved, and finding the people who want to walk alongside us.” —Toni Shiloh, Christy Award-winning author

My Impressions
“Not understanding you are enough to be loved. You already are loved.” He held her gaze. “And that love will never leave you.” She blinked rapidly. “That’s a promise you can’t make.”
What an exciting fictional world Susan L. Tuttle has created in her book, The Hidden Key of Brooke Sumner! As Book three of Treasures of Halstead Manor, I was curious. I wanted to read the book, but I hadn’t read the first two. I highly recommend reading the books in order to avoid spoilers. However, I was pleased to find Tuttle gives enough backstory to make the pieces fit, should this be your first! I loved this book!
Brooke has deep abandonment and trust issues stemming from a childhood of rotating foster or group homes. Always hoping that this time, she wouldn’t mess up and be returned to the system. Brooke ends up believing that she is not good enough for others to love, and closes herself off, before others can reject her. She enjoys working with the team that Caspar sets up ( Charlie’s Angels, anyone?) and begins to feel close to Natalie and Everleigh again, and even Storm. But she reminds herself:
“This wasn’t permanent. She wasn’t meant for good things. She wanted them. She worked so hard to be deserving of them. To be good enough. But she inevitably failed.”
About Storm. He was a young boy who had first met Brooke in a home. Finding 8-yr-old Brooke heartbroken, 9-yr-old Storm becomes her protector. In his mind, for life. The two age out of foster care, set up a treasure-finding business together, and are well on their way to falling in love. Then a customer named Annika drives them apart. Now Brooke has lost her last mooring.
Fortunately, Adam, a friend who helped the two start their original business, helps Brooke start over. But, when Brooke appears to be in danger, Adam calls in Storm to help. Talk about unwanted, unwelcome help that creates conflict in her soul!
There is a bit of a dual timeline involved in the story. My heart broke for the relationship of the cousins. But everyone has to make their own choices.
I loved Gertie! She is blind, but sharp as a tack and a former FBI agent. And her puns are so terrible, but amusing. What she lacks in eyesight, she more than makes up for in insight. She often encourages Brooke to see beyond the apparent traits of people ( especially Storm) and look for the heart. Brooke just can’t get past her feelings of being abandoned by Storm, She feels if she could just belong to a family, but Storm messed up her last chance. “I’m not asking you to go from feeling. I’m asking you to go from truth.” Gertie’s fingers softy pressed into Brooke’s arm. “Life is going to bump and bruise us, and in the process we feel hurt. Lost. Tossed about. But feeling those things doesn’t change the truth of God.” Her words held firm in a way Brooke only wished her own heart could. “He sees you. He wants to anchor you. To hold you when life’s battering away at you. And he wants to heal your heart in the aftermath.”
The suspense factor gets so tight! And the twists were so great! I also loved the author’s use of specific art to further explain the story themes. I would love to experience a museum of immersive art like Tuttle describes! I wish I could go back and reread this story again- for the first time!
I received a copy of the book from the author and publisher via JustRead Tours. I also bought my own copy. No positive review was required, and all opinions are my own.
Notable Quotables:
“If he quieted every disturbance in our life, we’d only see him as our fixer. We’d never know him as Jehovah Shalom, our God of Peace.” – Storm
“Wrong perceptions can lead to misguided actions,” -Adam
“Relying on others, thinking she belonged, always led to chaos and hurt.”
“A life without hope might feel safe, but it’s actually the most dangerous place to be. Without hope, our world turns dark.” – Storm
“But striving to be good all on your own all the time is exhausting. And impossible.” – Storm
“History depends on the lens with which you’re viewing it. If your lens is faulty, then what you see is distorted.”- Caspar
