The key to my future is hidden in the past. But can I face the dark family secrets buried in 1591 and make it back in time to save everyone I love?
The Kingsley, Mallory, Radcliffe heirs and I (the Langley heir) journey to our family estates on a mission. We must each gather a unique ingredient tied to our family’s elemental abilities for a long hidden incantation that will reveal what bound our families together centuries ago.
Across the ages, I’ve seen firsthand how dark magic has attacked our families and grown more powerful every time it hurts us. We need this vicious cycle to end, and the key to fighting our enemies is hidden in our history. Danger stalks us at every turn, and someone I love is kidnapped. I have no idea who took my loved one or where they went. But I know how far my enemies will go to prevent me from casting this spell, so I must do it.
The spell unexpectedly transports us back to 1591 England. To a time when our ancestors worked together with the Fitzgeralds to reseal an ancient evil, the Dark One. Can we unlock our families’ hidden histories and uncover how to fight this enemy, along with the Fitzgerald’s dark warlock back in our own time?
If you’re seeking magical family sagas that stretch across a thousand years and will keep you reading past midnight, love that endures for centuries, and exciting quests through time, join Kat on her next pulse-pounding adventure!

About the author, K.C. Tansley 
K.C. Tansley lives on a hill somewhere in Connecticut with her guardian Shih tzus, Bentley and Akira, who alert her to every squirrel and delivery person who dares to enter their domain. She tends to believe in the unbelievables–spells, ghosts, time travel–and writes about them.
Never one to say no to a road trip, she’s climbed the Great Wall twice, hopped on the Sound of Music tour in Salzburg, and danced the night away in the dunes of Cape Hatteras. She loves the ocean and hates the sun, which makes for interesting beach days.
The Girl Who Ignored Ghosts is her debut YA time-travel murder mystery novel. As Kourtney Heintz, she also writes award winning cross-genre fiction for adults.

My Thoughts 
I’ve been following Kat Preston and her friends since the very beginning of K.C. Tansley’s series, and I’m always glad to step back into their world of haunted heirlooms, family curses, and time slips that send you tumbling into history before you’ve quite caught your breath.
This fourth installment, The Girl Who Trusted Ghosts, wastes no time plunging Kat, Evan, and the other heirs into danger. Their task sounds deceptively straightforward: gather the ingredients needed for a long-hidden spell that might finally reveal what bound their families together centuries ago. Of course, nothing is ever simple in Kat’s world. Dark magic stalks their every move, kidnappings raise the stakes, and one ill-fated incantation hurls them straight into 1591 England — a time when their ancestors faced off against the Dark One himself.
What I continue to love about this series is the sense of continuity. Each book has its own adventure, but the threads of family history, betrayal, and legacy weave tighter and tighter the further we go. You can read this one on its own, but the experience is infinitely richer if you’ve been along for the whole ride.
Kat herself is growing in fascinating ways. She’s braver, more determined, and her connection to both her ancestors and her own abilities deepens here. Evan, too, comes into sharper focus, and their relationship—complicated by curses and centuries-old secrets—adds both tenderness and heartbreak. Watching them together makes the looming question of whether they’ll ever get a happy ending all the more poignant.
Tansley keeps the pacing taut, but what lingers for me are the details: the way ancestral ghosts become guides, the discovery of why some of the original families were destroyed, and the truth behind the split from six to four. These moments give the story weight, reminding us that the battle against darkness is never just about spells and enemies; it’s about the choices people make, generation after generation.
By the time I turned the last page, I felt like I’d been on a roller coaster—twists, plunges, and breathless pauses where you’re sure the next drop will finish you, only to find you’re strapped in for one more plunge. It’s exhilarating, and it leaves me more than ready for the conclusion in Book Five.
A great read, thoroughly engaging and captivating. If you’re looking for a magical family saga with stakes that stretch across a thousand years, and a heroine who has truly come into her own, this series delivers. I’m already signed up for wherever Kat’s journey takes us next.
Goes well with: beef and barley stew, rustic bread, and a strong mug of black tea.
