Detailed Guide to the Heart of the Frontier Trilogy
Book 1: Treasured Grace (2017)
The trilogy opens with the story of the eldest sister, Grace Martindale. Following the deaths of their parents, Grace assumes the role of protector and caregiver for her younger sisters, Hope and Mercy. To secure safe passage to Oregon Territory on a wagon train, Grace enters into a marriage of convenience with a minister who subsequently passes away during the journey. Stranded at the Whitman Mission as winter approaches, Grace relies on her skills as a healer and midwife to support both the white settlers and the local Cayuse tribe. Tensions flare when a measles epidemic ravages the Native American population, leading to growing hostility. Grace must work alongside the rugged fur trapper Alex Armistead to save lives while trying to protect her sisters from the violence brewing on the horizon.
Book 2: Beloved Hope (2017)
The second installment shifts focus to the middle sister, Hope Flanagan. Having survived the horrific attack at the Whitman Mission, Hope is living with her sisters in Oregon City. However, the physical and emotional scars of the massacre run deep; she grapples with intense trauma and the spiritual struggle of blaming God for her suffering. When the Cayuse men accused of orchestrating the massacre are captured and brought to trial, Hope is forced to decide whether she has the strength to testify. Meanwhile, Army Lieutenant Lance Kenner enters her life. While Lance offers patience and genuine affection, Hope fears that her painful secrets and the scars of her past will prevent her from ever being worthy of love again.
Book 3: Cherished Mercy (2017)
The final book in the trilogy focuses on the youngest sister, Mercy Flanagan. Having survived the Whitman Massacre as a young child, Mercy is now a resilient young woman who feels a deep calling to help ease the ongoing friction between white settlers and the indigenous tribes of the West. She travels to the Rogue River Valley to assist a family friend, Eletta Browning, through a difficult pregnancy. There, she witnesses the local white population demanding the complete removal or destruction of the native tribes. Working alongside Pastor Adam, Eletta's brother-in-law, Mercy must lean heavily on her faith to navigate the dangerous path toward peace as the territory stands on the brink of war.
What to Know Before You Start
Before diving into Heart of the Frontier, readers should be aware that the trilogy deals with real-life historical events. The Whitman Massacre of 1847 is the pivotal catalyst for the entire series. Because of this, the series addresses heavier themes than typical historical romances, including grief, post-traumatic stress, and the violent realities of frontier conflicts. Despite these gritty elements, Peterson maintains a strong, faith-based focus, emphasizing healing, forgiveness, and the power of faith in God to overcome trauma.
Practical Reading Advice for Fans
While some of Tracie Peterson's other historical novels can function as standalones, the books in this trilogy are deeply intertwined. The character arcs of the three sisters build directly upon one another, making it essential to start with Treasured Grace. If you enjoy the Pacific Northwest frontier setting, Peterson has explored similar historical landscapes in her other series, such as the Oregon Legacy series and the Heart of Alaska series. However, these are completely separate works with different characters and timelines, so there are no crossover requirements to worry about before starting this trilogy.
