Lone Star Sisters Books in Order

Susan Mallery's Lone Star Sisters novels follow Lexi, Skye, and Izzy Titan, whose father's wealth gives the family influence but little peace. Jed Titan expects control over his daughters' lives, and the sisters have different ways of dealing with that pressure. Their friend Dana Birch, a deputy, adds another perspective as romantic problems become entangled with a threat to the family in Titanville, Texas.

Under Her Skin opens with Lexi facing a financial crisis at her spa. Cruz Rodriguez needs an introduction to the social world her family occupies, and he offers money in exchange for a temporary engagement. The deal sounds practical, but their earlier connection and the attraction between them make pretending to be a couple much less manageable than either expects.

In Lip Service, Skye is a widow raising her daughter and trying to manage her place in the family. Mitch Cassidy, the man who once left her waiting at the altar, returns after serving as a Navy SEAL. His arrival brings old feelings into a life already shaped by responsibility, while his own wounds and the reasons for their separation stand between them and an easy reunion.

Straight from the Hip turns to Izzy after an oil-rig explosion damages her sight. Survival instructor Nick Hollister is supposed to help her move beyond withdrawal and learn how to face a changed life. His own concealed motives complicate that task, and suspicion about the explosion links Izzy's struggle to the wider trouble surrounding the Titans.

The sisters' romances unfold inside a family conflict that keeps growing.

Hot on Her Heels puts Dana opposite Garth Duncan, Jed's son and the sisters' half brother, whose anger toward their father threatens the people she wants to protect. Dana's attraction to him cannot erase her loyalties or his wish for revenge. The historical novella Wild Hearts reaches back to Zeke Titan and schoolteacher Alethea Harbaugh, providing a separate earlier romance connected to the family's Texas background rather than continuing Dana's contemporary story.

Start the present-day sequence with Under Her Skin, followed by Lip Service, Straight from the Hip, and Hot on Her Heels. Wild Hearts can accompany that sequence as a prequel, with its suffragette heroine and different time period giving the Titan name another context. The main books combine contemporary romance with family intrigue, secrecy, and physical danger, so publication order helps the larger conflict develop alongside each couple. This is a useful choice for readers who want sisters supporting one another while dealing with a powerful parent and men whose intentions require more than a little trust.
