Titan Protectors Books in Order

Titan Protectors is a newer branch of Cristin Harber's world, and the name tells you a lot. These books lean into close protection, bodyguard work, and the kinds of threats that follow people home. The scale can still be big, but the danger feels more immediate and personal.

Hide and Seek opens the series with Callum Hale, a former Army Ranger who now protects clients for a living. His assignment is Grace Willoughby, an illustrator hiding from an abusive ex-husband who refuses to let her go. That first book sets the tone for the series, survivors trying to rebuild, protectors who are good at taking a hit but worse at trusting anyone, and romance that grows out of sustained danger rather than one flashy mission.

The line stays consistent after that. Run and Hide pairs Hollywood figure Jules Lowry with Rhys, the former bodyguard she does not want to need, while paparazzi pressure and a stalker turn retreat into another kind of trap. Lost and Found moves to a former federal agent turned bodyguard who has to face the case that wrecked his career, then protect a single mother and true crime podcaster who may have stirred up the wrong truth.

These books are still romantic suspense, but the texture is slightly different from Titan and Delta. The focus is less on team raids and more on protection details, surveillance, hidden locations, old cases, abusive men, relentless media, and threats that keep finding cracks in the walls. Small towns, safe houses, and private assignments matter as much here as black ops skills.

That gives the series a more intimate feel. The heroines are often trying to reclaim ordinary life, safety, privacy, trust, the right to make their own choices, while the heroes are built to shield people but not always built to let themselves need anything in return.

If Titan is the big action family and Delta is the off-grid combat edge, Titan Protectors sits closer to the ground. It is still tense, still emotional, and still full of Harber's protective energy, but it narrows the lens onto the one person a hero has to keep alive, and what happens when that job stops being professional.
