Strong Justice

by Jon Land

Published 22 June 2010
Fifth-generation Texas Ranger Caitlin Strong is back, pursuing justice the Ranger way. She takes on the case of a Mexican girl on the run from white-slavers. For Caitlin, the case evokes memories of her legendary grandfather's run with the Rangers, even as it brings her face-to-face with a serial killer who's left a trail of bodies along the Mexico border. Pursuing the killer brings Caitlin to a sleepy Texas town suddenly riddled by violence and to the site of a major water find. The connection between these two disparate places lies buried beneath the plains of West Texas: a deadly weapon with the potential to give a new enemy the means to terrorize the United States. Her grandfather's past collides violently with Caitlin's present as she fights to save her world in the same border town where he fought to save his. Caitlin will learn, just as he did, that only strong justice can save the day. But this time, outmanned and outgunned, even that may not be enough to keep Caitlin Strong - and the country itself - alive.

Strong at the Break

by Jon Land

Published 21 June 2011
Fifth-generation Texas Ranger Caitlin Strong returns in an adventure with roots in a gunfight where her father shot down the cult-like leader of a separatist church. Two decades later, that man's son, Malcolm Arno, has become head of a militia movement bent on unleashing chaos and anarchy across the country. With all the guns and money he needs to wage a second Civil War, nothing seems to be standing in Arno's way. Until he runs afoul of Caitlin Strong. Already mired in one investigation of drug smuggling over the U.S.-Canadian border and another involving an Iraqi war veteran who claims the army is trying to kill him, Caitlin finds herself embroiled in the search for the kidnapped son of former outlaw Cort Wesley Masters. When the missing boy's trail leads to Malcolm Arno's Texas compound, the three cases converge in an explosion of violence that will put Caitlin to the ultimate test. From the frozen rivers of Canada to the desert wastelands of Mexico, the stage has been set for a battle like none Caitlin has ever faced before, where the stakes are nothing less than the survival of America as we know it.

The Present: Texas Ranger Caitlin Strong, Cort Wesley Masters, and his teenage boys, survive a terrifying gun battle. Caitlin and Cort Wesley pursue the perpetrators only to discover that the targets were actually the boys! That sets the two off on a trail winding through the past and present. Along the way they confront terrible truths dating all the way back to the opium smuggling that helped finance the Mexican Revolution. That is until the Texas Rangers, led by Caitlin's grandfather and great-grandfather, struck back with the aid of Emiliano Zapata, wiping out the early drug lords responsible. Now the remnants of that powerful criminal lineage are out for vengeance against Zapata's remaining relatives, including the late mother of Cort Wesley's two sons-and thus the boys are targets, too. The final battles of that war will take place in Texas with nothing less than the country's future at stake.

The investigation leads back to Texas and to the Chinese high-tech company awarded the contract to build the US' 5G network. Li Zhen, the company's founder, counts that as the greatest achievement of his career, but it hides his true motivations - nothing less than China's total domination of the United States. His plan is backed by elements of the Chinese underworld. Up against an army at Li's disposal, Caitlin blazes a violent trail across country and continent in search of secrets hidden in the past, but it's a secret from the present that holds the key.

Strong Light of Day

by Jon Land

Published 13 October 2015
Caitlin Strong is a fifth generation Texas Ranger as quick with her wits as she is with her gun. Over the years she's taken on all manner of criminals and miscreants, thwarting the plans of villains to do vast damage to the country and state she loves. But none of that has prepared Caitlin for an investigation that pits her against ruthless billionaire oilman Calum Dane, whose genetically engineered pesticide may have poisoned a large swath of the state. How that poisoning is connected to the disappearance of thirty high school students from a Houston prep school, including the son of her outlaw lover Cort Wesley Masters, presents Caitlin with the greatest and most desperate challenge of her career. As if that wasn't enough, she also has to deal with a crazed rancher whose entire herd of cattle has been picked clean to the bone by something science can't explain. The common denominator between these apparently disparate events is a new and deadly enemy capable of destroying the US economy and killing millions, a foe it will take far more than bullets to bring down. There's yet another player in the deadly game Caitlin finds herself playing: Russian extremists prepared to seize an opportunity to win a war they never stopped fighting. Caitlin's race to save the United States weaves through the present and the past, confronting her and Cort Wesley with the most powerful and dangerous enemies they've ever faced, human and otherwise. The Cold War hasn't just heated up; it's boiling over under the spill of a strong light only Caitlin can extinguish before it's too late.
