Davian has won a victory for the Augurs, but treachery surrounds him and his allies on all sides in the second book of the acclaimed Licanus Trilogy, in which fans of Robert Jordan and Brandon Sanderson will find much to admire. Following a devastating attack, an amnesty has been declared for all Augurs--finally allowing them to emerge from hiding and openly oppose the dark forces massing against the land of Andarra.

The Augur Davian and his new allies hurry north toward the ever-weakening Boundary, but fresh horrors along their path suggest that their reprieve may have come far too late. The new Northwarden, his ally in the Capital, contends with assassins and politicians and uncovers a dangerous secret. Meanwhile, their compatriot Asha begins a secret investigation into the disappearance of the Shadows. And Caeden races against time to fulfill a treacherous bargain, but as more and more of his memories return, he begins to realize that the two sides in this ancient war may not be as clear-cut as they first seemed.

As destiny calls, a journey begins. It has been twenty years since the god-like Augurs were overthrown and killed. Now, those who once served them - the Gifted - are spared only because they have accepted the rebellion's Four Tenets, vastly limiting their powers. As a Gifted, Davian suffers the consequences of a war lost before he was even born. He and others like him are despised.

But when Davian discovers he wields the forbidden power of the Augurs, he sets into motion a chain of events that will change everything. To the west, a young man whose fate is intertwined with Davian's wakes up in the forest, covered in blood and with no memory of who he is... And in the far north, an ancient enemy long thought defeated begins to stir.

The Licanius Trilogy is a relentless coming-of-age epic from the very first page.

Keita Ali is on the run. Like every boy on the mountainous island of Zantoroland, running is all Keita’s ever wanted to do. In one of the poorest nations in the world, running means respect. Running means riches—until Keita is targeted for his father’s outspoken political views and discovers he must run for his family’s survival. He signs on with notorious marathon agent Anton Hamm, but when Keita fails to place among the top finishers in his first race, he escapes into Freedom State—a wealthy island nation that has elected a government bent on deporting the refugees living within its borders in the community of AfricTown. Keita can stay safe only if he keeps moving and eludes Hamm and the officials who would deport him to his own country, where he would face almost certain death. This is the new underground: a place where tens of thousands of people deemed to be “illegal” live below the radar of the police and government officials. As Keita surfaces from time to time to earn cash prizes by running local road races, he has to assess whether the people he meets are friends or enemies: John Falconer, a gifted student struggling to escape the limits of his AfricTown upbringing; Ivernia Beech, a spirited old woman at risk of being forced into an assisted living facility; Rocco Calder, a recreational marathoner and the immigration minister; Lula DiStefano, self-declared queen of AfricTown and madam of the community’s infamous brothel; and Viola Hill, a reporter who is investigating the lengths to which her government will go to stop illegal immigration. Keita’s very existence in Freedom State is illegal. As he trains in secret, eluding capture, the stakes keep getting higher. Soon, he is running not only for his life, but for his sister’s life, too. Fast moving and compelling, The Illegal casts a satirical eye on people who have turned their backs on undocumented refugees struggling to survive in a nation that does not want them. Hill’s depiction of life on the borderlands of society urges us to consider the plight of the unseen and the forgotten who live among us.

A young woman follows winter across five continents on a physical and spiritual journey that tests her body and soul, in this transformative memoir, full of heart and courage, that speaks to the adventurousness in all of us.

Steph Jagger had always been a force of nature. Dissatisfied with the passive, limited roles she saw for women growing up, she emulated the men in her life—chasing success, climbing the corporate ladder, ticking the boxes, playing by the rules of a masculine ideal. She was accomplished. She was living The Dream. But it wasn't her dream.

Then the universe caught her attention with a sign: Raise Restraining Device. Steph had seen this ski lift sign on countless occasions in the past, but the familiar words suddenly became a personal call to shake off the life she had built in a search for something different, something more.

Steph soon decided to walk away from the success and security she had worked long and hard to obtain. She quit her job, took a second mortgage on her house, sold everything except her ski equipment and her laptop, and bought a bundle of plane tickets. For the next year, she followed winter across North and South America, Asia, Europe, and New Zealand—and up and down the mountains of nine countries—on a mission to ski four million vertical feet in a year.

What hiking was for Cheryl Strayed, skiing became for Steph: a crucible in which to crack open her life and get to the very center of herself. But she would have to break herself down—first physically, then emotionally—before she could start to rebuild. And it was through this journey that she came to understand how to be a woman, how to love, and how to live authentically.

Electrifying, heartfelt, and full of humor, Unbound is Steph's story—an odyssey of courage and self-discovery that, like Wild and Eat, Pray, Love, will inspire readers to remove their own restraining devices and pursue the life they are meant to lead.
